Is the YouTube algorithm radicalizing us?
Our new PNAS paper says: probably not!

Because we came up with a way to disentangle the causal effect of the algorithm.

The 'echo chamber' is a key explanation for online radicalization.
But the concept remains ill-defined.
What actually takes place within echo chambers?
In this book, we go inside 20 years of the "murder capital of the racist internet" to find out. 1/

A meta-analysis 105 studies finds that focusing on intrinsic goals (such as growth, relationships, community giving, & health) promotes well-being ( r= .24), whereas a focus on extrinsic goals (such as wealth, fame, & beauty) hurts well-being (r = -.22) https://t.co/Jpf3I1q8uB
As a researcher, I try my best to notice robust findings that go against my priors -- meaning that before seeing the results, I would have predicted the opposite.
Here is a recent & thought-provoking example, comparing the psychology of people who were born rich vs. became rich.
What predicts #cooperation?
A meta-analysis of 2,636 experiments finds that expectations of cooperation, social orientation, norms, and punishment predict cooperation.
Religiosity, time pressure, cognitive load, and hormones do NOT predict cooperation https://t.co/elDNwN3Xu4

Negative news gets clicks, so becomes more common. The result: Pervasive pessimism disconnected from reality. Many believe the economy is terrible (even when it's not) and are certain this is the worst time in history to live (when in many ways it's the best time).
Interesting study showing a significant association between social media use and worse emotional well-being at the between-person level but *not* the within-person level (lots of heterogeneity in within-person relations). https://t.co/5wKCHQMJKP
Much of unhappiness is a result of thinking that we have control over situations where we don't. Here's how understanding the "dichotomy of control" can lead to greater resilience and satisfaction in life. https://t.co/caBMj97LUa
