Nepali Prime Minister Pushpa Kamal Dahal will be on an official visit to China from September 23 to 30, during which he will attend the opening ceremony of the 19th Asian Games in Hangzhou, and meet President Xi Jinping as well as several other leaders. Dahal believes the visit will strengthen and deepen the traditional friendly relations between China and Nepal. Another aim of the visit is to seek further avenues of bilateral cooperation.

On September 7, the first batch of imported goods under the China-Nepal Transit Transport Agreement, consisting of 15 tons of turmeric powder, arrived in the Nepali capital of Kathmandu after transiting through China. The turmeric powder was imported by Nepal from Vietnam and transported to Kathmandu via Tianjin Port in northern China and the Zhangmu-Tatopani border point. Both China and Nepal have positively commented on this achievement. The Nepali side stated that the successful transportation of the first batch of goods under the China-Nepal Transit Transport Agreement signifies the beginning of a transformative journey toward enhanced economic cooperation, increased trade volumes and shared prosperity. Chinese Ambassador to Nepal Chen Song noted that the successful implementation of the China-Nepal Transit Transport Agreement will diversify Nepal's international trade and facilitate Nepal's trade with the whole world. In the future, the time and cost of importing and exporting goods via China will be further reduced, which will have a positive impact on Nepal's trade.

In contrast to the substantial progress made by China and Nepal in areas such as cross-border transportation, Nepal has been facing ongoing issues with another neighboring country, India, recently. In May, the Nepali government was infuriated by a mural displayed within the newly inaugurated Indian Parliament building. This mural, titled "Akhand Bharat," included the Chinese Tibet region, parts of Afghanistan, as well as the entire territories of Nepal, Pakistan, Bangladesh, Sri Lanka and Myanmar. As early as May 2020, India inaugurated a road connecting the Indian mainland to the border region, passing through the disputed territory of Kalapani, which is claimed by Nepal.

In fact, the incidents of the mural and road inauguration reflect the ongoing contestation and counter-control between Nepal and India, which has been a longstanding feature of their relationship. For a long time, India has adopted a paternalistic approach in its policies toward Nepal. While providing some support and assistance, India often resorts to rude and unilateral actions toward Nepal.

Nepal is located north of the Himalayas and is surrounded by Indian territory in the west, south and east. It heavily relies on India for economic and external communication, including the transit of essential goods such as food, medicine and fuel through India. India is Nepal's largest trading partner. In addition to the geographical dependence on India for external connectivity, Nepal is also deeply influenced, and even controlled, by India in political, social and security domains.

However, this has become a bargaining chip for India's attempt to control Nepal. In history, India has repeatedly used the agreement on transit through Nepal as a coercive diplomatic tool, threatening and implementing blockades against Nepal to force the Nepali authorities to adopt domestic and foreign policies that align with India's wishes. This has caused serious dissatisfaction among various levels of Nepali society and the government. Nepal has also actively sought alternative transportation routes to reduce its dependence on India. In 2017, Nepal officially joined the Belt and Road Initiative, which was a clear indication to India that Nepal is a country with the right to make independent choices.

Objective conditions determine that Nepal will continue to rely to varying degrees on the transit routes provided by India in the past, present and future, which means that Nepal cannot completely sever ties with India. In this situation, how to handle relations with India without compromising national sovereignty, independence and territorial integrity while ensuring smooth communication between Nepal and the outside world has always been the greatest challenge for Nepal's foreign policy. It is precisely because of this, after Prachanda assumed the position of Prime Minister for the third time, he made his first visit to India. 

In contrast, China strictly adheres to the Five Principles of Peaceful Coexistence and never interferes in Nepal's internal affairs. All factions in Nepal actively seek development and close relations with China. After assuming the position of Deputy Prime Minister, Narayan Kaji Shrestha stated that the country will "maintain relationships of equi-proximity with both our neighbors," namely China and India, emphasizing that the focus of governance will be on "containing inflation, maintaining reserves, raising capital expenses, narrowing the trade deficit and lowering interest rates" to promote Nepal's economic development. The results of Prachanda's visit are highly anticipated.

Many people say that this round of Israeli-Palestinian conflict erupted quite suddenly, and on the surface, it does seem so. Hamas launched a surprise attack on the Israel's military, catching them off guard and resulting in significant casualties that have shocked the world. Israel's retaliatory actions are bound to lead to more bloodshed and escalation of violence. Even though none of us want to see this happen, it is difficult to prevent it from occurring. International peace efforts are far from strong enough in the face of the Israeli-Palestinian conflict. This is an unavoidable fact and requires a more powerful collective effort from the international community to change it.

From a deeper perspective, this conflict is not sudden and has a certain inevitability. It once again announces to the world, through bloodshed and loss of life, that if fundamental solutions are not implemented for the Palestinian issue, and if the peace process is not promoted, bloodshed and conflict will recur. This is actually quite evident, but it has long been ignored by Western countries that bear the primary responsibility and influence in the Palestinian issue.

For many years, China has repeatedly called on the international community to prioritize the Palestinian issue on the international agenda on major multilateral occasions such as the United Nations. It has emphasized the need to advance the "two-state solution" with a stronger sense of urgency. Not long ago before the outbreak of this conflict, Permanent Mission of China to the UN was still stressing this point. Now, the necessity and urgency have been elevated to another level, given the high cost paid by Palestine, Israel, and the entire Middle East.

It's necessary to recognize that the Israeli-Palestinian issue is a complex conglomerate of problems, and external interference is one of the main reasons why this problem has not been resolved and even intensifies hatred. The bias and interference by Western countries, led by the US, in the Israeli-Palestinian issue have been evident for a long time, and historical Middle East conflicts have often had US involvement behind the scenes. And after the escalation of the Israeli-Palestinian conflict, the quick decision of the US and some Western countries to take sides not only does not help solve the problem but also adds fuel to the fire. Considering the large number of innocent civilians killed and injured in the conflict over the past two days, the immediate priority of the international community should be to urge both sides to cease fire quickly in order to prevent further humanitarian disasters.

A report from the United Nations Conference on Trade and Development shows that the prolonged closure and military operations carried out by Israel during the occupation of Gaza from 2007 to 2018 have pushed Gaza's economy to the brink of collapse. Today, it has become one of the poorest and most volatile areas in the world. It can be said that this large-scale armed conflict between Palestine and Israel once again proves that the means of seeking absolute security, under the guise of peace by the US and the West, cannot achieve true peace and tranquility. It also exposes the essence of the US new Middle East strategy. We urge the US and other Western countries to stop this practice and truly participate in the Middle East peace process.

Middle East peace is by no means a road without a future. The key is to start walking the right path from now on, rather than taking the wrong path or even going back. According to media reports, this round of conflict between Palestine and Israel has already caused nearly 1,000 deaths and thousands of injuries on both sides. Moreover, the war may also spread to other countries. The latest development is that Israel and the armed group Hezbollah in Lebanon have engaged in a firefight. Many people worry whether this event will eventually lead to the "Sixth Middle East War."

At this moment, the international community should take urgent action. The United Nations issued a statement on October 7, calling it a "dangerous precipice," strongly condemning the attacks on civilians, and calling for an end to violence. UN Secretary-General António Guterres urged "all diplomatic efforts to avoid a wider conflagration." The UN Security Council plans to hold a closed-door meeting on the current situation between Palestine and Israel Sunday afternoon local time in New York to discuss solutions. Fundamentally, all parties involved in the Middle East peace process, including Palestine and Israel, must work toward creating conditions for the realization of the "two-state solution."

It has been 50 years since the Fourth Arab-Israeli War (also known as the Yom Kippur War, Ramadan War, October War) and 30 years since the signing of the Oslo Accords. War or peace? The Middle East is once again at a historical crossroads. The international community must take decisive and effective diplomatic actions to urge both sides to stop violence as soon as possible, exercise maximum restraint, and especially prevent the window of opportunity for peace from being closed by conflicts. China has always supported the convening of a larger-scale, more authoritative, and influential international peace conference to create conditions for the resumption of negotiations. This proposal is now more necessary and urgent.

Huawei launched new products ranging from smart screens, the MatePad and watches to the new Harmony OS NEXT system at a highly anticipated event in Shenzhen, South China's Guangdong Province on Monday, making a high-profile comeback to the market amid reported a chip breakthrough and years-long US sanctions.

While the event did not reveal the details of the closely watched Mate 60 series, consumers are still enthusiastic about the release, viewing it as a symbolic moment for the Chinese tech giant to regain lost ground in the consumer business and move forward to rival industry giants such as Apple.

The company flooded major Chinese social media platforms under hashtags such as #FarAhead, since the surprisingly presale of the Mate 60 series on August 29. The series has since become a big seller across the country.

The Monday launch event intensified the fanfare across the country, attracting live broadcasts and livestreaming by more than 100 media outlets. Audiences are also crying out "Far Ahead Rivals" in each product announcement on-site. 

Yu Chengdong, CEO of the Huawei Consumer Business Group, said at the opening that the company is ramping up efforts and working overtime to produce its devices, fulfilling market demand for the newly released handsets. "Thanks to Chinese consumers' all-out support to Huawei," Yu said.

Previously, some anticipated a formal detailing of the phone's specs - in particular, the chipsets in the Mate 60 series - at the Monday event, which reportedly utilizes the Kirin 9000s chip, featuring either 7-nanometer (nm) or 5-nm process technology. 

Huawei has kept tight-lipped about the capabilities of the chip. But industry analysts believe that the handset shows that the US-sanctioned tech giant has finally found a way through and will welcome its magnificent turnaround after years of hard struggles, especially in the high-end smartphone market.

Demand for the Mate 60 Pro has been strong since its surprising launch on August 29, and the shipment plan for the second half of 2023 has increased by about 20 percent to 5.5-6 million units. Based on this market trend, cumulative shipments of the Mate 60 Pro are expected to reach at least 12 million units within 12 months after the launch, Kuo Ming-Chi, an analyst at TF International Securities, said in a note.

Huawei's "undeniable influence" on industries and stock markets is coming back, Kuo said. He noted that Huawei's comeback is actually a good thing for consumers. It can force Apple to step out of its comfort zone and innovate more aggressively.

At a time when mobile phone consumption is relatively sluggish, the return of Huawei's high-end mobile phones is a landmark event for the bottoming out of the mobile phone consumer market, Adela Guo, a research director at IDC Asia Pacific, told the Global Times on Monday.

In the short term, it is expected to drive an upsurge in the domestic mobile phone consumer market. It will also make competition in the high-end mobile phone market more intense, Guo said.

Monday also marked two years since the return of Meng Wanzhou in 2021. Meng, now a rotating chairperson of Huawei, was arrested by Canadian authorities in December 2018 at the request of the US government.

Some netizens said a stronger Huawei returning to the center stage of global tech innovation may be considered as "a slap in the face" to the US government's ruthless suppression and attack on the leading Chinese tech company, especially as the planned event date marked second anniversary of Meng's safe return from Canada to China.

"Huawei's mobile phone business, which has been unreasonably suppressed for more than three years, has broken through major obstacles and been completely rebuilt. We can see that all the Huawei partners, Huawei fans and the media are quite excited with a festive atmosphere on scene," Jiang Junmu, a Shanghai-based veteran industry expert and close follower of Huawei, told the Global Times on Monday.

Huawei also unveiled the latest progress of its self-developed operating system HarmonyOS at the event, with the new release of Harmony OS NEXT. 

"A coordination of software and hardware will help Huawei construct a more perfect, complete system that will help it return to the international market," Jiang said.

There are now more than 30 operating systems in China that are based on HarmonyOS open source, covering industry terminals, mobile phones, tablets and home terminals. In total, there are approximately 600 million users, ranking third in the world, Huawei founder Ren Zhengfei said in a recent interview with Liu Yadong, Dean of the School of Journalism and Communication at Nankai University.

Ren said that if China establishes its own standard system, it will definitely be better than that of the US.

Ren compared the system to "clothes," saying that the US clothes were mended again and again, and there were patches everywhere. But Huawei has made new "clothes" in recent years. "We will directly make standards better than those in the US. In addition to being used in China, it is used all over the world," Ren said.

Huawei may encounter more difficulties, but at the same time it becomes more prosperous, Ren said.

The EU's anti-subsidy probe into Chinese new energy vehicles (NEV) is based on subjective assumptions, lacks sufficient evidence and goes against WTO rules, China's Ministry of Commerce (MOFCOM) said on Wednesday, responding to an EU decision to conduct the probe.

We express strong dissatisfaction and firm opposition to the EU decision, the MOFCOM said in a statement posted on its website on Wednesday.

China will closely follow Europe's investigative procedure and firmly safeguard the legitimate rights and interests of Chinese companies, the MOFCOM said.

The EU requires negotiation with the Chinese side under extremely short notice and failed to provide effective materials for negotiation, which has seriously infringed China's rights, according to the ministry.

The ministry noted that in the 10th China-EU High-level Economic and Trade Dialogue, held in late September, the Chinese side clearly stated that the EU's proposed probe is blatant protectionism and aimed at protecting the EU's industry under the guise of "fair trade," the moves of which will seriously disrupt and distort the global automotive industrial and supply chain, of which the EU has a part, and result in negative impacts on China-EU trade and economic ties.

China urged the EU to exert caution in applying trade remedy measures, considering the big picture of maintaining the stability of global industrial and supply chains and the China-EU comprehensive strategic partnership, the MOFCOM said.

"The EU should encourage deepened cooperation in the new energy industry which has NEVs as one of its spearheads, and create a fair, non-discriminatory and predictable market environment for the common development of the China-EU EV industry," the MOFCOM said.

In recent years, China's EV industry has seen rapid development thanks to its unremitting technological innovation and building up of a complete industrial and supply chain. And Chinese EVs have been favored by consumers including those in the EU.

According to auto consultancy Inovev, 8 percent of new EVs sold in Europe as of September this year were Chinese, up from 6 percent in 2022 and 4 percent in 2021.

In 2022, Chinese automakers exported 545,244 NEVs to Europe, accounting for 48.66 percent of all NEV exports, data from the China Passenger Car Association showed.

On Wednesday, the China Association of Automobile Manufacturers (CAAM) expressed its strong opposition to the EU’s decision.

It is a clear fact that the Chinese EV market is a fiercely competitive market and not one supported and protected by subsidies, the industry association said, adding that the EU’s stubbornness in launching the probe regardless of the fact constitutes a blatant protectionist behavior and will definitely impede the global development of the EV industry and pose hazard to the global carbon neutralization process.

The Chinese and European automotive industries are partners, not rivals, and the development of the automotive industry needs fair competition, not protectionism, the CAAM said.

Taikonauts of the Shenzhou-14 manned spaceflight mission crew are conducting their third spacewalk operation on Thursday, which marked the first extravehicular activities (EVA) after the China Space Station completed its T-shape basic structure assembly on November 3.

As of 11:16 am, taikonauts have successfully opened the airlock and the Shenzhou-14 mission commander Chen Dong first came out of the cabin. Chen will be followed by his fellow crewmember Cai Xudong for the Thursday spacewalk. Liu Yang, the only female crewmember, will be supporting them on the inside, according to the China Manned Space Agency.

During the Thursday operation, which is the seventh at the China Space Station executed by taikonauts, spacewalking taikonauts are expected to carry out works including the installation of connecting devices to bridge space station modules to facilitate future spacewalk missions and the elevation of the panorama camera on the Wentian lab module. 

The Global Times learned from mission insiders that the Thursday spacewalk will also mark a first in the use of the combination of the large and small robotic arms to support taikonauts activities all over the mega space station combination.

Having been connected at the ends, the combination of the large and small robotic arms could provide a larger operation range for taikonauts that extends to 15 meters, meaning it will be able to cover almost every corner of the space station combination, according to mission insiders. 

The second space station lab module Mengtian conducted successful transposition in orbit at 9:32 am on November 3, marking the completion of the China Space Station's T-shape basic structure assembly and a key step forward toward the completion of the space station.

China has successfully tested a parachute system during a recent launch of a Long March-3B carrier rocket, confirming an ability to narrow the landing area by 80 percent, making the landing more precise, the Global Times learned from the China Academy of Launch Vehicle Technology (CALT) on Friday.

The test was conducted on May 17 when the rocket was successfully launched carrying the 56th satellite for China's BeiDou Navigation Satellite System.

After analysis of experimental data and debris at the site, the academy found that the parachute system can fly in accordance with arranged landing lines and precisely push the detached part of the rocket to the landing area. The system narrowed the landing area range by 80 percent, according to the academy.

The test laid the foundation for large-scale application of the system in future projects, the academy noted.

According to the academy, the parachute system was independently developed by CALT to improve the safety of the landing area of rocket debris at the inland launch site.

Encased atop one of the rocket's four boosters, the high-tech parachute system was activated after the booster separated from the rocket and fell back to a preset altitude in order to control the separated body's altitude and direction and guide it to the arranged landing area, the academy told the Global Times.

The precise controlling of the system was achieved after various rounds of optimization.

The main optimization was carried out in the electrical subsystem. Engineers integrated the design of the parachute system in the boosters with that of the rocket fairings, and also integrated the electrical equipment within the parachute system, achieving a weight reduction of 30 kilograms, according to CALT.

Chinese regulators have required apps and WeChat mini programs by domestic developers to register via the same system as domestic websites. Experts said the move will help optimize registration and management procedures and mechanisms for apps and mini programs while helping to better deal with the issues that have arisen with the expansion of the internet such as online fraud and pornographic content.

According to a notice released by WeChat on Wednesday, starting from September 1 mini programs on the platform have to register with the Internet Content Provider (ICP) system before they can become available on WeChat. The registration has to be completed in accordance with national regulations and rules such as the Law on Combating Telecom and Online Fraud, and Internet Information Service Management Measures, the notice said.

The move came one day after China's Ministry of Industry and Information Technology (MIIT) issued a notice requiring all domestic app developers to complete registration procedures.

China started to require ICP registration in 2000. The mechanism has played an active role in promoting the development of the internet in China over the past two decades. Along with the rapid development of the internet, apps have become the main content carrier of internet service and should register with the same requirements as websites, including registering the developers' real name, network resources and services, according to the notice.

Along with the rapid development of the internet in China over the years, apps and mini programs became widely used. So it is necessary to standardize and optimize the registration and management mechanism for these products, Xie Yongjiang, executive director of the Internet Management and Legislation Research Center at Beijing University of Posts and Telecommunication, told the Global Times on Wednesday.

Xie highlighted some issues that have come along with the wide usage of apps and mini programs such as gambling, telecom fraud and pornographic content in education apps for children. Strict registration and review procedures will help to prevent such problems in the future, he said.

This optimized mechanism will also help deal with emerging problems such as private information leakage given the rapid development of big data and artificial intelligence technologies, the expert said.

Mini programs already on the platform also have to finish registration by the end of March 2024 or they will be shut down starting April 1, 2024.

According to the MIIT notice on Tuesday, app developers who started providing apps in the Chinese market before the notice was issued have to register with provincial-level communications administrations where the developer is based between September 2023 and March 2024. MIIT will carry out an inspection in April-June 2024 and developers who have not registered by that time will be dealt with according to the law, the notice said.

The notice stressed that app developers in the fields of journalism, publishing, education, film and television, and religion should also provide approval documentation from provincial-level communication administrations while registering their apps.

Along with EG.5, a sublineage of the Omicron variant, being classified as a "variant of interest" by the World Health Organization (WHO), the topic of a third COVID-19 wave has triggered discussions among Chinese netizens in recent days with many sharing their infection experiences. Experts noted that the COVID-19 situation in China is still stable and that there is no need to panic.

Some netizens on Monday who said on social media that they had been reinfected a third time noted that their symptoms were lighter than previous infections. However, some shared different experiences.

The current COVID-19 infections are more hidden, but generally still at a relatively stable level. There isn't an obvious seasonal pattern for COVID-19 transmission, but usually it will show a small infection peak every five to six months. Generally, "the infection peak is decreasing, with no impact on the country's overall prevention work," Lu Hongzhou, head of the Third People's Hospital of Shenzhen, told the Global Times on Monday.

Generally speaking, fewer people have been infected for a third or more time in Shenzhen, South China's Guangdong Province, according to Lu.

Peng Jie, director of the Difficult Infectious Disease Center at Nanfang Hospital in Guangzhou, also in Guangdong, said since the peak reinfection wave in May, some patients who thought they had ordinary fevers only found out they had COVID-19 after nucleic acid testing. Among them, only a few were infected for the third time, and their symptoms are relatively light, said Peng, according to a report issued on the Guangdong authorities' WeChat account on Saturday.

National fever outpatient treatment and the number of severe COVID-19 cases have shown a fluctuating downward trend, according to the Chinese Center for Disease Control and Prevention (China CDC).

In July alone, the Chinese mainland reported 455 new serious cases of COVID-19, with 65 deaths. The patients had underlying health issues, and no one died of respiratory failure due to COVID-19, the China CDC said in its latest report issued on August 3. In June, the country reported 1,968 new serious cases, with 239 deaths, said the China CDC.

Based on the July data, the genome sequences of 9,591 local COVID-19 samples were all Omicron variant strains, covering 116 evolutionary branches, and the XBB variant strains were the main circulating ones, said the report released by the China CDC.

Due to the highly infectious nature of COVID-19 and the natural decrease in antibodies in individuals over time, basically most people can expect to be infected one to three times in a year. However, "for people with normal immune function, it will not have a significant impact on them," Lu explained. 

As long as the COVID-19 mutation doesn't completely break away from the Omicron subbranch, an individual will have a cross-immune memory, so when an individual encounters the EG.5 COVID-19 strain, it will respond fast and produce antibodies, according to Lu.

EG.5 was first reported in February, and designated as a variant under monitoring in July, according to a report released by the WHO on August 9. There has been a steady increase in the proportion of EG.5 reported globally. From July 17 to 23, the global prevalence of EG.5 was 17.4 percent, a notable rise from the data reported in the week from June 19 to 25, when the global prevalence of EG.5 was 7.6 percent, according to the WHO.

Lu suggested people with underlying health issues receive COVID-19 vaccinations regularly, including nasal spray vaccines or other multivalent vaccine strategies.

The dumping of nuclear-contaminated wastewater from the Fukushima nuclear power plant in Japan has raised concerns among Chinese citizens about the state of the marine environment. Chinese environmental authorities on Monday vowed to strengthen the monitoring of marine environmental pollution through multiple means, including conducting baseline surveys of marine pollution and utilizing satellites for monitoring.

China has launched its third marine pollution baseline survey, with the goal of completing a thorough investigation and assessment by 2025, said Wang Juying, the director of the National Marine Environmental Monitoring Center, at the ministry's monthly press conference on Monday.

According to Wang, this survey follows the overall approach of "understanding the current situation, identifying problems, analyzing causes, and proposing countermeasures," and focuses on China's coastal waters and the country's 283 bays, with the aim of understanding the baseline levels of various pollutants in China's jurisdictional waters, the ecological conditions of various bays, and the impact of human activities. 

"The survey aims to comprehensively grasp the basic state and trends of the marine ecological environment," Wang said.

China previously conducted the first and second national marine pollution baseline surveys in 1976 and 1996, respectively.

Hu Songqin, deputy director of the Department of Marine Ecology and Environment of the Ministry of Ecology and Environment, mentioned during the conference that the recent successful launch of a satellite to serve environmental protection and disaster management will significantly enhance data support and emergency response capabilities for sudden water environmental pollution events.

She stated that the Ministry of Ecology and Environment will actively collaborate with relevant research institutions and coastal regions, making effective use of data sources from monitoring systems. 

"These will provide crucial technical support for addressing sudden environmental events, pollution incidents, investigations of key risk sources, and enhancing marine ecological environmental governance capabilities," she noted.

In response to Japan dumping the contaminated water from the Fukushima nuclear plant into the ocean, the Ministry of Ecology and Environment has stated the specific measures that China has taken in terms of marine radiation environment monitoring.

At present, the ministry is actively conducting marine radiation environment monitoring in areas under China's jurisdiction for the year 2023, guided by a focus on critical regions, comprehensive coverage of jurisdictional waters, and a thorough understanding of key pathways, according to the ministry.

The ministry also vowed that in the future it will continue to strengthen relevant monitoring efforts, closely track and assess the potential impact of of contaminated water from the Fukushima nuclear plant on China's marine environment, and effectively safeguard the national interests and public health.

In 2021 and 2022, the ministry organized marine radiation environment monitoring in areas under China's jurisdiction, which provided insight into the baseline condition of the marine radiation environment in these regions. The monitoring results indicated that there were no abnormal levels of artificial radioactive isotopes in the seawater and marine organisms in China's jurisdictional waters, and overall, the concentrations remained within the historical fluctuation range.

Here’s a good idea for the next presidential candidate debate: They can insult each other about their ignorance of statistics.

Actually, it’s a pertinent topic for political office seekers, as public opinion polls use statistical methods to measure the electorate’s support (or lack thereof) for a particular candidate. But such polls are notoriously unreliable, as Hillary Clinton found out in Michigan.

It probably wouldn’t be a very informative debate, of course — just imagine how Donald Trump would respond to a question asking what he thought about P values. Sadly, though, he and the other candidates might actually understand P values just about as well as many practicing scientists — which is to say, not very well at all.
In recent years criticism about P values — statistical measures widely used to analyze experimental data in most scientific disciplines — has finally reverberated loudly enough for the scientific community to listen. A watershed acknowledgment of P value problems appeared this week when the American Statistical Association issued a statement warning the rest of the world about the limitations of P values and their widespread misuse.

“While the p-value can be a useful statistical measure, it is commonly misused and misinterpreted,” the statistical association report stated. “This has led to some scientific journals discouraging the use of p-values, and some scientists and statisticians recommending their abandonment.”

In light of these issues, the association convened a group of experts to formulate a document listing six “principles” regarding P values for the guidance of “researchers, practitioners and science writers who are not primarily statisticians.” Of those six principles, the most pertinent for people in general (and science journalists in particular) is No. 5: “A p-value, or statistical significance, does not measure the size of an effect or the importance of a result.”

What, then, does it measure? That’s principle No. 1: “… how incompatible the data are with a specified statistical model.” But note well principle No. 2: “P-values do not measure the probability that the studied hypothesis is true, or the probability that the data were produced by random chance alone.” And therefore, always remember principle No. 3: “Scientific conclusions … or policy decisions should not be based only on whether a p-value passes a specific threshold.”

In other words, the common convention of judging a P value less than .05 to be “statistically significant” is not really a proper basis for assigning significance at all. Except that scientific journals still regularly use that criterion for deciding whether a paper gets published. Which in turn drives researchers to finagle their data to get a P value of less than .05. As a result, the scientific process is tarnished and the published scientific literature is often unreliable.
As the statistical association statement points out, this situation is far from merely of academic concern.

“The issues touched on here affect not only research, but research funding, journal practices, career advancement, scientific education, public policy, journalism, and law,” the authors point out in the report, published online March 7 in The American Statistician.

Many of the experts who participated in the process wrote commentaries on the document, some stressing that it did not go far enough in condemning P values’ pernicious influences on science.

“Viewed alone, p-values calculated from a set of numbers and assuming a statistical model are of limited value and frequently are meaningless,” wrote biostatistician Donald Berry of MD Anderson Cancer Center in Houston. He cited the serious negative impact that misuse and misinterpretation of P values has had not only on science, but also on society. “Patients with serious diseases have been harmed. Researchers have chased wild geese, finding too often that statistically significant conclusions could not be reproduced. The economic impacts of faulty statistical conclusions are great.”

Echoing Berry’s concerns was Boston University epidemiologist Kenneth Rothman. “It is a safe bet that people have suffered or died because scientists (and editors, regulators, journalists and others) have used significance tests to interpret results,” Rothman wrote. “The correspondence between results that are statistically significant and those that are truly important is far too low to be useful. Consequently, scientists have embraced and even avidly pursued meaningless differences solely because they are statistically significant, and have ignored important effects because they failed to pass the screen of statistical significance.”

Stanford University epidemiologist John Ioannidis compared the scientific community’s attachment to P values with drug addiction, fueled by the institutional rewards that accompany the publication process.

“Misleading use of P-values is so easy and automated that, especially when rewarded with publication and funding, it can become addictive,” Ioannidis commented. “Investigators generating these torrents of P-values should be seen with sympathy as drug addicts in need of rehabilitation that will help them live a better, more meaningful scientific life in the future.”

Although a handful of P value defenders can still be found among the participants in this discussion, it should be clear by now that P values, as currently used in science, do more harm than good. They may be valid and useful under certain specific circumstances, but those circumstances are rarely relevant in most experimental contexts. As Berry notes, statisticians can correctly define P values in a technical sense, but “most statisticians do not really understand the issues in applied settings.”

In its statement, the statistical association goes a long way toward validating the concerns about P values that have been expressed for decades by many critical observers. This validation may succeed in initiating change where previous efforts have failed. But that won’t happen without identifying some alternative to the P value system, and while many have been proposed, no candidate has emerged as an acceptable nominee for a majority of the scientific world’s electorate. So the next debate should not be about P values — it should be about what to replace them with.
