“Analysis challenges slew of studies claiming ocean acidification alters fish behavior”

Here’s an interesting new paper in climate change ecology that states, “Using data simulations, we additionally show that the large effect sizes and small within-group variances that have been reported in several previous studies are highly improbable.”

I [Lizzie] wish I were more surprised, but mostly I was impressed they did the expensive work to try to replicate these other studies and somehow managed to get it published, given that “[t]he research community in the field of ocean acidification and coral reef fish behaviour has remained small.”

And here’s a news report with more background.

I’ve heard from some very important Harvard professors that the replication rate in psychology is quite high—indeed, it is statistically indistinguishable from 100%. I guess it’s a bit lower in other fields. We should all aspire to the greatness that is Ivy League psychology.
