It's been quite a year for hypothalamic development. With this heroic analysis of developmental cell lineage, coupled with earlier multimode-based gene regulatory network analysis, the prosomere model looks like it has passed into history.

All our work on replicability in the last decade has taught me that it's not a good use of resources to try and predict replicability in the first place since it's neither a good goal to achieve nor diagnostic of specific problems. It's a search for shortcuts, easy answers to complex questions.

There's no rationale, no theory, no evidence that connects chasing replicability to actual scientific progress or discovery. We're looking for ways to bypass the laborious scientific process of exploration. It's a pity that we waste our increasingly limited research resources on futile searches.

Imagine: If we had a crystal ball that tells us what are the discoveries to be made, we wouldn't have to do science in the first place. Apparently that's some scientists' scientific ideal. Rather than doing science. So many weird ontological and epistemic assumptions to unpack.

The first one is not a test of replicability. It is a test of generalization. It is important to stop conflating these.
