Clever thing they do in Boston: They make the bus to the airport seem like a train. You transfer from the train. It looks like it's running on train tracks. Addresses that whole "oh no I don't want to transfer to a bus" anxiety.

And, more generally, we applied consistent terminology: * Reproducibility = same data, same analysis * Robustness = same data, different analyses * Replicability = same question, different data These are examples of repeatability, and are components of the broader concept of credibility.

You have a data set and you torture it until it confesses a publishable story. You literally run loops testing millions of assumptions, exclusions, and model specifications. You end up in a subspace where things look pretty robust but this subspace is just 5% of reasonable analyses.

Nature meta-research project puts claims in social-science paper to the test. Refs in last post I'm interested in Econ and Psych so I focused on that: Econ had about the same rate of "not reproducible" analyses as Psych and a worse rate then Political Science.
