A 15-year bibliographic analysis identified systematic gender bias across Wikipedia

Research suggests articles on Wikipedia are about as reliable as 'accurate' sources

Studies from Nature, The Guardian, the Journal of Clinical Oncology, and the Canadian Library Association, among others, did not identify significant errors, particularly in articles related to academic topics. The site is still considered an exploratory, tertiary source subject to systemic biases from its human editors, especially within controversial topics.

China has blocked the Wikipedia domain since 2015

The Chinese language version of the site had been blocked intermittently since 2004 due to pages featuring topics deemed controversial by the Chinese communist party, including the 1989 Tiananmen Square protests and Taiwan.

Women work harder for Pulitzers

While the Pulitzers have never been segregated by gender, a 2012 study by the University of Missouri found female winners required significantly more elite credentials—Ivy League degrees, experience at top newspapers, and the like—than their male counterparts.

Philip Roth once tried to correct details on one of his novel's Wikipedia pages

The Wikipedia entry for Roth's 2000 novel "The Human Stain" alleges that the book was based on the life of Anatole Broyard, a Black American writer who "passed" for white, something he shared in common with the main character in Roth's novel, though Roth said that wasn't true. When Roth tried to correct the error, Wikipedia editors told him he would need a secondary source to back up his claim.

Why are there as many males as females?

Pretty much every species breaks down with an equal sex-ratio, with roughly the same number of males as females. But on the surface, it appears that most species wouldn't need many males to keep the population growing, with their energy-efficient, abundant sex cell production. So why is it equal? Scientists argue an equal ratio is the most evolutionarily stable. Learn about this quirk of biology here.

Understanding the causes, effects, and prevalence of algorithmic bias

Found in search engines, hiring and college admissions tools, facial recognition systems, and other software, algorithms act on the rules they are programmed with, which may be authored by individuals unaware of their own biases.

A guide to sabermetrics, the empirical analysis of baseball statistics

The science of baseball overturned a century of assumptions about which metrics matter most. The approach originated key categories like WAR (wins above replacement, which tries to summarize a player's total contribution by estimating how many more wins this player generated compared to a replacement-level player) and wOBA (or weight on-base average, which measures not only hits but also walks and their outcomes in the score).

The prominent role of women in the Easter story

In the first century, women's testimony was not legally admissible in Jewish courts—the historian Josephus wrote that their accounts were not admissible based on a prejudiced view of women. Scholars who argue for the historical reliability of the resurrection point to this as counterintuitive evidence: no one fabricating the story would have chosen women as the prime witnesses.

Jane Austen used satire to critique women's place in society
