Research Interests


Overall, what I’m interested in is what happens when people change.

In intelligence, this follows looking at what happens after interventions. When an intervention that raises intelligence ends, what happens to the participants? Do they change their behavior? Do the effects last (they don’t)? Why don’t the effects last?

In meta-science, what happens when we as scientists come across research that we disagree with? Do we change our beliefs as the Bayesians would have it? Do we ignore the research?

Furthermore: why do we keep believing society is changing for the worse, starting with our children being the downfall of civilization? It cannot be the case that the human race has been in decline for millennia. Why do we keep thinking it is?
