An even more entertaining way of illustrating strategic use of language to go around explicitly using the term "insignificant results"

A nice comic way of illustrating HARKing

Last week I had the pleasure and honour to give a talk on the value of preregistrations and registered reports to improve the confidence we have for science to the fascinating @againstpseudocu.bsky.social .

Result 2: Equilibrium bundles exhibit substantial dispersion in utility. - Strong evidence against WE (marked with X). (11/n)

Result 1: Prices reliably converge to computationally hard regions. - Compute confidence ellipsoids from data - Plot against complexity regions - Large overlap both when WE does not exist (left figure) and when it does (right figure). (10/n)

Data against phase transition in treatments where WE does not exist.

Using the prices and payoffs of goods, we can map the computational difficulty of the budget problem in a 2-dimensional space. In the yellow region, the budget problem is most difficulty to solve, both for humans and for computers. (6/n)

After two years, I am so happy to be back to the ESA conference in Brno hosted by @econmuni.bsky.social. Looking forward to catching up with colleagues. :) If you are curious to see how computational complexity interacts with general equilibrium, attend my talk on Saturday 10:40-11:40.

We thank all the speakers and attendees of the Workshop. We brought together researchers working in diverse topics and applying diverse methods. We had talks on decision complexity, cognitive constraints, neural learning, regulatory systems, market equilibria & more!

Currently in Pittsburgh until May for a research visit, drop me a line if you're around! Thank you to @alistairecon.bsky.social at #universityofpittsburgh and Steve Spear at @carnegiemellon.bsky.social for hosting me.
