> People who deactivated Facebook for the six weeks before the election reported a 0.060 standard deviation improvement in an index of happiness, depression, and anxiety, relative to controls who deactivated for just the first of those six weeks. People who deactivated Instagram for those six weeks reported a 0.041 standard deviation improvement relative to controls.

Can anyone translate? Random web search find suggests multiplying by 37 to get a percentage, which sounds very questionable, but even then these improvements seem negligible.

This doesn't really line up with my lived experience. Getting myself out of shitty platforms and community spaces improved my mental state significantly (although the damage that's been done remains).

From the paper PDF (https://www.nber.org/system/files/working_papers/w33697/w336...):

> We estimate that users in the Facebook deactivation group reported a 0.060 standard deviation improvement in an index of happiness, anxiety, and depression, relative to control users. The effect is statistically distinguishable from zero at the p < 0.01 level, both when considered individually and after adjusting for multiple hypothesis testing along with the full set of political outcomes considered in Allcott et al. (2024). Non-preregistered subgroup analyses suggest larger effects of Facebook on people over 35, undecided voters, and people without a college degree.

> We estimate that users in the Instagram deactivation group reported a 0.041 standard deviation improvement in the emotional state index relative to control. The effect is statistically distinguishable from zero at the p = 0.016 level when considered individually, and at the p = 0.14 level after adjusting for multiple hypothesis testing along with the outcomes in Allcott et al. (2024). The latter estimate does not meet our pre-registered p = 0.05 significance threshold. Substitution analyses imply this improvement is achieved without shifts to offline activities. Non-preregistered subgroup analyses suggest larger effects of Instagram on women aged 1824.

So, ELI5 level.

People who use Facebook also may feel depression, from very strong to none at all. In the middle of this interval there's the "expected value" point, sort of an average level of feeling depressed. This point is at an equal distance from the "most depressed users" group, and from the "not depressed at all" group. Let's call this distance of depression strength a "standard deviation".

Now, the users who stopped using Facebook became slightly less depressed, by 6% of that "standard deviation" range. If you buy a small coke at a McDonald's, then take one sip, you make it about 6% smaller. It's not unnoticeable (you've made that refreshing sip), but about 15 more such sips still remain!

In other words, there is an effect which can definitely be noticed ("statistically significant"), but it's not a big deal either.
