The importance of investor mood for startups: This paper shows that on a day with☀️, investors are happier… and significantly more likely to fund startups! (Also a sign that the decision to fund early-stage startups is not as rational as some investors would have you believe)

Learning a second language is great for communicating, but doesn't bring spillover cognitive benefits, even if you were told it did. Recent research, including a meta-analyses of 157 studies, has found no advantage in any cognitive dimension for learning additional languages.

You may have seen makeup used to confuse facial recognition systems but it usually looks insane & obvious to humans. This study found a way to apply makeup in a way that confused machines 98% of the time while looking natural to other people. arxiv.org/abs/2109.06467

Research shows leaders inspire when they give vivid images of the future, but they tend to talk about abstract goals instead. This paper shows a trick to inspiring others: "mental time travel" - painting a vivid picture of what the world will look like when you achieve your goal.

Mixed Iraqi Christian & Muslim soccer teams reduced prejudice on the field, but not off it. Mixed Palestinian & Israeli camp bunks increased odds of cross-cultural friendship, lowering prejudice. So close contact can reduce prejudice, but lasting change starts with friendship.

However, soccer stars do seem to reduce prejudice. 👇
Our parasocial relationship with celebrities can reduce hate: a study of 15 million tweets found that when ⚽️ superstar Mohamed Salah joined Liverpool, hate crimes dropped in the area by 18% & anti-Muslim tweets by half compared to other areas. Open paper: cambridge.org/core/journals/…

If you have 90 minutes this weekend, and want to play a free game that teaches entrepreneurial strategy & mindsets 👇
If you want to invest in (or run) startups, you should play the short free game I authored that teaches the latest evidence & approaches for evaluating startups. Look at data, interview founders and get lots of personal feedback. We just hit 3,000 players! interactive.wharton.upenn.ed…

The first org chart was made for the New York & Erie Railroad in 1854, solving issues of control & coordination in ways we still use. Not only is it full of plant-inspired beauty, it also combines a map of the physical railroad & one of company structure. mckinsey.com/business-functi…

The sketchy part of the connection between💰 and 😀 This study found increased consumption, not earnings, increases wellbeing. And, in a confirmation of what you might have feared, there is evidence in the paper that conspicuous consumption makes you happiest 😬

Blending cultures is awesome. What if Star Wars & Fahrenheit 451 were classic Russian lubok wood prints (Note samovar)? Or else Ottoman miniatures (details like the scimitar lightsaber)? But wait, there's more! All 🇷🇺 art is by Andrey Kuznetsov & 🇹🇷 art is by @_Muratpalta 1/
