Thrilled to announce our new paper in @PNASNews! Do the moral values people endorse change with the seasons 🌤️? My co-authors and I present evidence that suggests (for some moral values) the answer is yes. pnas.org/doi/10.1073/pnas.23…

Excited to share our paper in @PNASNexus, with @ProfJessTracy, Nick Rule, & Laura Tian! We show that the muscles people use to pose a smile—and the intensity of those activations—reveals personality, enabling others to form accurate personality judgments. academic.oup.com/pnasnexus/a…

Smile variation leaks personality and increases the accuracy of interpersonal judgments

Abstract. People ubiquitously smile during brief interactions and first encounters, and when posing for photos used for virtual dating, social networking,

Does materialist science destroy existential meaning? @Ian_Hohm, @LiminusVisuals, and I argue here that yea, it does. But that doesn't mean you have to choose between science and meaning ...journals.sagepub.com/doi/epu…

Super excited to announce our new paper in @PNASNews! @ProfJessTracy, @FriedrichMGoetz, and I analyzed all US senators' tweets from 2013-2021 and found that tweets discussing greed in society receive greater support and spread more widely

Very excited about this paper!! We argue that seasonal effects are important. We review some of the diverse literature on seasonal effects, outline a conceptual framework for thinking about them, and give practical suggestions for studying them. 🌸☀️🍂❄️

My @TEDTalks on why we moralize effort is now up. Based on work w/ @pkpiff (who gets a cameo), @BizarroPolitix, @gregoryscience, Hyunjin Koo & led by @JaredCelniker. Thanks to TED (who chose against my suggested title: Working in the Age of Effort Porn) ted.com/talks/azim_shariff_d…

Around the world, people who work hard are often seen as morally good -- even if they produce little to no results. Social psychologist Azim Shariff analyzes the roots of this belief and suggests a...

This study🤯Tracked tax records from Florence, Italy in 1427 (before Leo DeVinci was born) and matched them with descendants in 2011. Descendants of the richest decile are 12% wealthier than descendants of the poorest decile. Wealth inequality inherited across 600 years!

This paper argues that the massive modularity debate is confused, ill-posed, and based on the most fundamental misunderstanding one can have in psychology: a confusion about the level of reduction (or analysis) at which one is approaching the mind. 1/x psyarxiv.com/7syvr

The average length of written English sentences went from 63 words in the 1500s to 14 in 1950. Artifact or some sort of cultural change?

Surprised by this level of arbitrariness? Don’t be. Discretion is the silent killer in our justice system, and it haunts every step—from decisions to arrest, if/how to charge, bail, plea offers, peremptory challenges of jurors, and, of course, sentencing👇 theatlantic.com/ideas/archiv…

How a Spreadsheet Could Change the Criminal-Justice System

A lack of data instills trial-court judges with enormous, largely unrestrained sentencing power.

My latest piece is out today in @AreoMagazine. It’s on the crucial distinction between the proximate and ultimate levels of analysis -- and the utility of that distinction for psychology. Hope you find it interesting. areomagazine.com/2020/07/20/…

We've seen lots of comparisons between countries and U.S. states on distancing measures to reduce disease spread - but how do we measure up to other species? (Worse than ants, but better than Tasmanian Devils.) See interview on my new co-authored paper: sciencemag.org/news/2020/08/…
