🧵🧵🧵 Lots of people talking about assortative mating, wherein people choose mates who are similar to themselves on specific traits or overall desirability. Less well-known is that people who are desirable on one trait (eg intelligence) also tend to be higher on other desirable traits (eg kindness). Even less well known is that assortative mating CAUSES desirable traits to be correlated in the population over evolutionary time. 🧵Assortative Mating & the Evolution of Desirability Covariation🧵 1/

@SteveStuWill That pattern is very often found with outcome variables (e.g., job performance, social succes). The question is why would five presumably independent traits consistently show this specific pattern. The General Factor of Personality (GFP) seems a plausible explanation.

“Personality predicts occupational success. Conscientiousness is the strongest predictor... Extraversion, agreeableness, and openness are also positively correlated with occupational success, whereas neuroticism is negatively correlated with it.” stevestewartwilliams.com/p/12-things-ev…

@jz_psych @AndrKerber1 Thanks for sharing. Nice study....but, uh..not a single reference to the GFP? :0)

@RolfZwaan Gefeliciteerd Rolf!

I don't often share personal news, but this is one I can't keep to myself. I'm absolutely over the moon to announce the birth of my grandson, Hugo Addis Zwaan, earlier today. I can't wait to start this new adventure as a granddad to this already wonderful little person!

A recent article on Flow in the Guardian, that also discusses our work on this topic. Together with @Doria59054590 and @ProfABBakker . theguardian.com/science/articl…

@SteveStuWill That seems like a function of the General Factor of Personality, which indeed is correlated with well-being in such a way.

The Big 5 personality traits strongly predict life satisfaction (r = .8 - one of the largest effects I’ve seen in a psychology paper). stevestewartwilliams.com/p/5-new-findin…

@DeBie_Hendrik @giladfeldman @ugent I like the idea. It is somewhat a return to the 'old' system in which departments could hire a PhD student every couple of years.

@julianetzel @wille_bart Great work! Here is a also paper that provides an additionele way to look at personality and vocational interest: link.springer.com/article/10.100…

🚨 PREPRINT ALERT 🚨 After 4-5 years of work, I am happy to share a preprint of what is my proudest achievement to this day. It entails everything I have learned over the past 10 years and more... osf.io/preprints/psya…

@erikbij Yes, the old literature on fatigue is fantastic. They really did a lot of nice work then.

Our review on heart rate variability in mental fatigue is now online in Biological Psychology. With Arpad Csatho and Andras Matuz. doi.org/10.1016/j.biop…

@SpencrGreenberg Was there a Dunning-Kruger effect?

In a study we ran, we asked people if they'd ever taken a commercial/professional IQ test, and if so, if they remembered their score, and if "yes," what their score was. We then measured their IQ ourselves. Guess how accurate or inaccurate their reported numbers were... 🧵

@cremieuxrecueil GFP no? Are you sure? link.springer.com/article/10.100…

When someone proposes a new general factor, they should try to see if there's any twin or genomic data available to check if etiological factors match up with the proposed phenotypic model. For - GFP: no - d: no - p: no - g: yes! If causal evidence came first, we'd see fewer!

@paulg @cremieuxrecueil See this one for the relationship between personality (GFP) and creativity: #d=gs_qabs&t=1688918153799&u=%23p%3DYppuDo4Jru0J" target="_blank" rel="nofollow noopener">scholar.google.com/scholar?hl=nl&…

So much for the concept of the moody creative genius. One of the strongest correlations in this huge study is the *negative* correlation between creativity and "uneven temper." (via @cremieuxrecueil)

@drtcp @Subeer Yes indeed :0) psycnet.apa.org/record/2016-55…

Very excited to start this project in collaboration with several international experts including Susanne Becker (Düsseldorf), Dimitri van der Linden @Dimitri_329 (Rotterdam), and Nicolas Silvestrini (Geneva)!

Great news 🥳🥂! Our research project exploring the role of effort in the effects of pain on cognitive functioning was funded by @FWOVlaanderen. Looking forward to work on this with a fantastic team of collaborators: @Dimitri_329, Susanne Becker, and Nicolas Silvestrini.

What puts you into a “flow state?”

@wille_bart 🤣🤣

Reviewer 2 just reviewed my paper on narcissism as a paper on 'neuroticism'. How's your day going?

@gmiller Yes, probably true to a large extent as a very low GFP relates to all kinds of problems. Although the GFP has a broader range as it also includes positive or, at least, social desirable traits.

@Dimitri_329 Not sure. To the extent that it looks like there's a GFP, it might be mostly tapping into the p factor (e.g. less adaptive subfactors of neuroticism, Introversion, disagreeableness). Haven't kept up on this debate in a few years though

In human intelligence, there's a 'g factor' that captures a lot of the positive correlations across cognitive abilities. In mental health, there seems to be a 'p factor' that captures a lot of the positive correlations across psychopathologies (mental disorders).
