~15 months isn’t necessary a target for the future. I think we could actually increase the gap to ~1.5 years going forward. But yes, the reasons for that would be to get the best balance between getting more repeated measurements (which increases the power, loosely speaking, of our estimates), being able to capture meaningful trends (looking at cross-year data, most things don’t seem to change dramatically in the course of only 12 months), and reducing survey fatigue. That said, whatever the average frequency of the survey going forward, I expect there to be some variation as we shuffle things around to fit other organisations’ timelines and to not clash with other surveys (like the EA Groups Survey) and so on.
Ah I see. Is the ~15 months gap between surveys to avoid survey fatigue? Or are there other reasons?

Got it, thanks for the info!
