Digital tech sentences to ponder

The first generation who engaged with digital technologies has reached the age where risks of dementia emerge. Has technological exposure helped or harmed cognition in digital pioneers?

…Use of digital technologies was associated with reduced risk of cognitive impairment (OR = 0.42, 95% CI 0.35–0.52) and reduced time-dependent rates of cognitive decline (HR = 0.74, 95% CI 0.66–0.84). Effects remained significant when accounting for demographic, socioeconomic, health and cognitive reserve proxies.

So maybe digital tech is not so bad for us after all?  You do not have to believe the postulated relatively large effects, as the more likely conclusion is simply that, as in so many cases, treatment effect in the social sciences are small.  That is from a recent paper by Jared F. Benge and Michael K. Scullin.  Via the excellent Kevin Lewis.
