Controlling leaders aren't helping employees. Instead, providing employees with autonomy increases their well-being and makes them more pro-social. Autonomy is a basic psychological need. Great leaders know it and act on it.

A dumber smartphone makes you smarter—and happier. Instead of browsing on their phone, people spent time socializing, exercising, and enjoying nature. They could also focus better. Not just correlation. Causal evidence. 📖 Source: academic.oup.com/pnasnexus/ar...

📢 Promotie "Gezichten van de Bureaucratie" Maandag verdedigt Isa Bertram haar proefschrift over stereotypen over ambtenaren. 🎓 Iedereen heeft wel een mening over ambtenaren – en vaak geen positieve. Ambtenaren vinden we saai, inflexibel en ze ook nog vroeg naar huis. 📷 Foto's Jan Banning.

Giving employees autonomy can be great. But sometimes, it backfires. In a natural experiment, we found: ⚡ In calm times, empowering leadership energizes employees. 🔥 During an intense crisis, empowering leadership drains them. @pmreview.bsky.social @henricovanroekel.bsky.social

💸 Paying people to #vaccinate sounds smart... but it didn’t work. 🚫 No effect on vaccination rates. 🏠 Worse: people at the same address (who didn’t get paid) were less likely to get boosted. ⚠️ Incentives can backfire. #BehavioralScience jamanetwork.com/journals/jam... @sebjilke.bsky.social

We love to think empowering #leadership is always a good thing. But sometimes, it’s not. 🤔 In a natural experiment we found: ⚡ In calm times, empowering leadership fuels energy. 🔥 But during a crisis, it drains employees. During a crisis, leaders need to step up, not step back.

Zodra je zegt dat je een beperking hebt, sta je 1-0 achter. We schreven er een opiniestuk over in de NRC. In een van de studies zagen we dat sollicitanten die in hun brief aanstipten dat ze een beperking hebben, hun kans om uitgenodigd te worden met 35 procent zagen slinken.
