The paper is by David Hugh-Jones, and this is from the research summary:
The study examined whether people from different countries were more or less honest and how this related to a country’s economic development. More than 1500 participants from 15 countries took part in an online survey involving two incentivised experiments, designed to measure honest behaviour.
Firstly, they were asked to flip a coin and state whether it landed on ‘heads’ or ‘tails’. They knew if they reported that it landed on heads, they would be rewarded with $3 or $5. If the proportion reporting heads was more than 50 per cent in a given country, this indicated that people were being dishonest…
The countries studied – Brazil, China, Greece, Japan, Russia, Switzerland, Turkey, the United States, Argentina, Denmark, the United Kingdom, India, Portugal, South Africa, and South Korea – were chosen to provide a mix of regions, levels of development and levels of social trust.
The study’s author Dr David Hugh-Jones, of UEA’s School of Economics, found evidence for dishonesty in all the countries, but that levels varied significantly across them. For example, estimated dishonesty in the coin flip ranged from 3.4 per cent in the UK to 70 per cent in China. In the quiz, respondents in Japan were the most honest, followed by the UK, while those in Turkey were the least truthful. Participants were also asked to predict the average honesty of those from other countries by guessing how many respondents out of 100 from a particular country would report heads in the coin flip test. However, participants’ beliefs about other countries’ honesty did not reflect reality.
This is interesting:
“Differences in honesty were found between countries, but this did not necessarily correspond to what people expected,” he said. “Beliefs about honesty seem to be driven by psychological features, such as self-projection. Surprisingly, people were more pessimistic about the honesty of people in their own country than of people in other countries.
And consider this from Hugh Jones:
“I suggest that the relationship between honesty and economic growth has been weaker over the past 60 years and there is little evidence for a link between current growth and honesty,” said Dr Hugh-Jones. “One explanation is that when institutions and technology are underdeveloped, honesty is important as a substitute for formal contract enforcement. Countries that develop cultures putting a high value on honesty are able to reap economic gains. Later, this economic growth itself improves institutions and technology, making contracts easier to monitor and enforce, so that a culture of honesty is no longer necessary for further growth.”

Jones, by the way, makes it clear there are a variety of kinds of honesty, and inferences from any single test should be limited. For Japan in particular the measured level of honesty depends critically on which test is applied. The real lesson of the study may simply be that most groups are dishonest, and people are not even honest with themselves about their views of the dishonesty of others. Honesty depends a good deal on context too. On some of these questions, see some skeptical comments from Kevin Drum.
If you are looking for simple correlations: “…at individual level, there is no evidence that religious adherence is associated with honesty.” How about having a Ph.d.?
