Two summers ago, we published a post (Colada 98: .htm) about a study reported within a famous article on dishonesty (.htm). That study was a field experiment conducted at an auto insurance company (The Hartford). It was supervised by Dan Ariely, and it contains data that were fabricated. We don’t know for sure who fabricated those data, but we know for sure that none of Ariely’s co-authors – Shu, Gino, Mazar, or Bazerman – did it . The paper has since been retracted (.htm).
That auto insurance field experiment was Study 3 in the paper.
It turns out that Study 1’s data were also tampered with…but by a different person.
That’s right: Two differentpeople independently faked data for two different studies in a paper about dishonesty.
The paper’s three studies allegedly show that people are less likely to act dishonestly when they sign an honesty pledge at the top of a form rather than at the bottom of a form. Study 1 was run at the University of North Carolina (UNC) in 2010. Gino, who was a professor at UNC prior to joining Harvard in 2010, was the only author involved in the data collection and analysis of Study 1 .

As the number of casualties from COVID-19 ballooned at an alarming rate last year, some feared that government officials were failing to report several coronavirus-related losses and the actual death toll was much higher worldwide.
While the official count shows more than 5 million people have died of the disease, a new study of underreported casualties in several countries indicates that COVID has actually killed hundreds of thousands more people than government records document.
The HBS researchers gathered the reported monthly numbers of deaths during the pandemic in each of the 51 countries from a variety of sources, including reports in the New York Times and the European Commission’s database, Eurostat. They compared that data to figures from the same months for the past three to five years to calculate excess deaths. Subtracting the number of official COVID deaths for each country helped them gauge potential underreporting.
In fact, countries with more stringent policies in place did, on average, have 59 percent higher unexplained excess deaths—that is, 159 deaths for every 100 reported for COVID.

Should eco-conscious investors support a company that’s developing innovative solutions to climate change—even if that company is also a major polluter?
The market’s answer to this question has been a resounding “no,” as evidenced by the investment policies that exclude traditional oil producers from most so-called sustainable funds. But this stance eliminates some of the most prolific and influential producers of green innovation, including Exxon Mobil, BP, and Chevron, according to recent research by Harvard Business School Professor Lauren Cohen.
Faced with mounting concerns about climate change, oil companies are diversifying their businesses, putting money toward renewable energy sources and green technology. While sustainable funds shun fossil fuel producers, which contribute half of the world’s greenhouse gases, Cohen’s study suggests that these companies could also play a key role in stemming the damage.
