Is social media dying? How much has Twitter changed as it became X? Which party now dominates the conversation?
Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has transformed.

Are #smartphones and #socialmedia harming a generation?
This is a hotly debated and often polarizing debate. So we surveyed over 120 experts on the topic to see where there was genuine consensus (or not), like experts have previous done for climate change.

Another study showing sample sizes in psychology increase over time. Several reasons, but that the increase is stronger in journals with stronger open science policies is interesting. Triangulation with other studies (done in the discussion) suggests better research practices are one cause.

We combined experience sampling data with smartphone usage data to examine the bidirectional association between well-being and smartphone use over time.

There is very real reason to worry about the dynamic emerging between Washington and Moscow when it comes to Ukraine. But there is also very real reason to believe that Ukraine and Europe can create a better outcome.
