Risky business: linking _Toxoplasma gondii_ infection and entrepreneurship behaviours across individuals and countries | Proceedings of the Royal Society B: Biological Sciences
Using a saliva-based assay, we found that students (n = 1495) who tested IgG positive for Toxoplasma gondii exposure were 1.4× more likely to major in business and 1.7× more likely to have an emphasis in ‘management and entrepreneurship' over other business-related emphases. Among professionals attending entrepreneurship events, T. gondii-positive individuals were 1.8× more likely to have started their own business compared with other attendees (n = 197). Finally, after synthesizing and combining country-level databases on T. gondii infection from the past 25 years with the Global Entrepreneurship Monitor of entrepreneurial activity, we found that infection prevalence was a consistent, positive predictor of entrepreneurial activity and intentions at the national scale, regardless of whether previously identified economic covariates were included. Nations with higher infection also had a lower fraction of respondents citing ‘fear of failure' in inhibiting new business ventures. While correlational, these results highlight the linkage between parasitic infection and complex human behaviours, including those relevant to business, entrepreneurship and economic productivity.

Infection and entrepreneurship | Proceedings of the Royal Society of London B: Biological Sciences
Abstract

Disciplines such as business and economics often rely on the assumption of rationality when explaining complex human behaviours. However, growing evidence suggests that behaviour may concurrently be influenced by infectious microorganisms. The protozoan Toxoplasma gondii infects an estimated 2 billion people worldwide and has been linked to behavioural alterations in humans and other vertebrates. Here we integrate primary data from college students and business professionals with national-level information on cultural attitudes towards business to test the hypothesis that T. gondii infection influences individual- as well as societal-scale entrepreneurship activities. Using a saliva-based assay, we found that students (n = 1495) who tested IgG positive for T. gondii exposure were 1.4× more likely to major in business and 1.7× more likely to have an emphasis in ‘management and entrepreneurship' over other business-related emphases. Among professionals attending entrepreneurship events, T. gondii-positive individuals were 1.8× more likely to have started their own business compared with other attendees (n = 197). Finally, after synthesizing and combining country-level databases on T. gondii infection from the past 25 years with the Global Entrepreneurship Monitor of entrepreneurial activity, we found that infection prevalence was a consistent, positive predictor of entrepreneurial activity and intentions at the national scale, regardless of whether previously identified economic covariates were included. Nations with higher infection also had a lower fraction of respondents citing ‘fear of failure' in inhibiting new business ventures. While correlational, these results highlight the linkage between parasitic infection and complex human behaviours, including those relevant to business, entrepreneurship and economic productivity.

Fear and Loathing in Psychology - The Unz Review
Warne and Astle looked at 29 best-selling undergraduate textbooks, which is where psychology students learn about intelligence, because less than 10% of graduate courses offer an intelligence option.

3.3% of textbook space is dedicated to intelligence. Given its influence, this is not very much.

The most common topics start well, with IQ and Spearman’s g, but do not go on to the best validated, evidence-led Cattell-Horn-Carol meta-analytic summary, but a side-stream, speculative triarchic theory from Sternberg; and a highly speculative and non-specific sketch of an idea about multiple intelligences Gardner. The last is a particular puzzle, since it really is a whimsical notion that motor skill is no different from analytical problem solving. All must have prizes.
Commonly, environmental influences are discussed, genetic ones rarely.

Education or Indoctrination? The Accuracy of Introductory Psychology Textbooks in Covering Controversial Topics and Urban Legends About Psychology: http://sci-hub.tw/https://link.springer.com/article/10.1007/s12144-016-9539-7

Twenty-four leading introductory psychology textbooks were surveyed for their coverage of a number of controversial topics (e.g., media violence, narcissism epidemic, multiple intelligences) and scientific urban legends (e.g., Kitty Genovese, Mozart Effect) for their factual accuracy. Results indicated numerous errors of factual reporting across textbooks, particularly related to failing to inform students of the controversial nature of some research fields and repeating some scientific urban legends as if true. Recommendations are made for improving the accuracy of introductory textbooks.

this is completely unrelated AFAICT:

Mapping the scale of the narcissism epidemic: Increases in narcissism 2002–2007 within ethnic groups: https://www.sciencedirect.com/science/article/pii/S0092656608000949

The increasing numbers of Asian-Americans at the UCs over time may have masked changes in narcissism, as Asian-Americans score lower on the NPI. When examined within ethnic groups, Trzesniewski et al.’s data show that NPI scores increased significantly between 2002 and 2007 at twice the rate of the yearly change found over 24 years in Twenge et al. (2008a). The overall means also show a significant increase 2002–2007. Thus the available evidence suggests that college students are endorsing progressively more narcissistic personality traits over the generations.

Birth Cohort Increases in Narcissistic Personality Traits Among American College Students, 1982–2009: http://journals.sagepub.com/doi/abs/10.1177/1948550609355719

Both studies demonstrate significant increases in narcissism over time (Study 1 d = .37, 1982–2008, when campus is controlled; Study 2 d = .37, 1994–2009). These results support a generational differences model of individual personality traits reflecting changes in culture.

could this just be a selection effect (more people attending)?

You also need to understand that the world is not as simple as John Oliver makes it sound when you watch his show. I know he’s funny and has a cool English accent, but he also has no fucking clue what he is talking about, only he doesn’t know that.

The Toxoplasma Of Rage | Slate Star Codex
The idea of liberal strategists sitting down and choosing “a flagship case for the campaign against police brutality” is poppycock. Moloch – the abstracted spirit of discoordination and flailing response to incentives – will publicize whatever he feels like publicizing. And if they want viewers and ad money, the media will go along with him.

Which means that it’s not a coincidence that the worst possible flagship case for fighting police brutality and racism is the flagship case that we in fact got. It’s not a coincidence that the worst possible flagship cases for believing rape victims are the ones that end up going viral. It’s not a coincidence that the only time we ever hear about factory farming is when somebody’s doing something that makes us almost sympathetic to it. It’s not coincidence, it’s not even happenstance, it’s enemy action. Under Moloch, activists are irresistably incentivized to dig their own graves. And the media is irresistably incentivized to help them.

Getting High On Your Own Supply | Slate Star Codex
If you optimize for the epistemic culture that’s best for getting elected, but that culture isn’t also the best for running a party or governing a nation, then the fact that your culture affects your elites as well becomes a really big problem. If focus groups tell you that your campaign ads need to be more emotional, more zero-sum, more simplistic, and more oriented to the white working class, it’s pretty scary if you don’t reflect before making your whole ideology’s culture more emotional, zero-sum, simplistic, and oriented to the white working class.

Luckily this has an easy solution. From the same Tim Harford article I cited earlier:

Last year, three researchers — Seth Flaxman, Sharad Goel and Justin Rao — published a study of how people read news online. The study was, on the face of it, an inquiry into the polarisation of news sources. The researchers began with data from 1.2 million internet users but ended up examining only 50,000. Why? Because only 4 per cent of the sample read enough serious news to be worth including in such a study. (The hurdle was 10 articles and two opinion pieces over three months.) Many commentators worry that we’re segregating ourselves in ideological bubbles, exposed only to the views of those who think the same way we do. There’s something in that concern. But for 96 per cent of these web surfers the bubble that mattered wasn’t liberal or conservative, it was: “Don’t bother with the news.”
