On January 6, 2021, the US Capitol was attacked by a mob of Trump supporters. Exactly 5 years later, the free access to my new overview paper "The Psychology of Conspiracy Mentality" will expire. Coincidence, Elsevier? 🤐

This idea started in my 2019 ESCON keynote (with Felicitas Flade) and came to life thanks to the incredible talent of Verena Heidrich who turned this vague idea into a paper I am really proud of.

Across 5 pre-registered experiments, we found:
People don’t just categorize more when meta-contrast is high —
They prefer to use the dimension with the stronger relative meta-contrast when several are available.

Imagine the features that define a category (like skin color for race or skin texture for age). If these cues fall into two tight, non-overlapping clusters, categorizing is easy.
If they’re messy and (almost) overlapping, not so much.

Result from our registered Report suggest that minority and majority members do not lump the respective Outgroup and individuate the Ingroup (a cross-race effect) symmetrically. Specifically, White US American showed an greater categorization of Black than White targets in a Who-Said-What Paradigm.

And we found it: we connected it to basic tendencies of exploration vs. exploitation. In lush conditions, it is safe to exploit and feed off the oversupply. In dire conditions, it seems advisable to seek new shores, a better life, to explore.

That seemed like a very Western, modern, potentially even short-lived characteristic to care about. So, that was the puzzle: Why (ideological) beliefs? The “beeline” was born! We tried to come up with something at least as grandiose and ancient as friend or foe.

Trying to publish this, we faced many hurdles, but a major one was: But why? Why SHOULD people care about beliefs? The sexiness of the warmth primacy idea is that it resonates: sure, I want to know whether someone’s friend or foe. But ideology?

Evaluative priming tasks frequently assume that averaging across faces of a race will provide a good measure of race evaluation. Manuel Becker argues that faces have many more features that might play a role. Osthofen #facemeeting

Ipek Oruc brings welcome vision science expertise to Osthofen #facemeeting. The "Face diet" method records all faces people encounter during their waking hours. People do see more own-race faces in their environment - and limited other-race exposure is associated with increased ORE.

...in fact: it holds literally across the globe that the same facial features useful to distinguish individuals within one "race" are highly correlated (read: virtually identical) for other "races"...

Directing participants' gaze to the allegedly diagnostic area does.....absolutely nothing. People have the belief that the respective areas are particularly distinctive, but there is no evidence attention to these areas helps face memory.
