Shifting research focus comes with the risk of reduced impact
An analysis of millions of scientific papers and patents shows that the further a researcher or inventor moves from their previous work, the less cited their latest work will be.

Does anyone know of open datasets where people have asked participants to explicitly define non words? We are pulling together an experiment now and hoping to r/o iconicity and wordlikeness as content drivers

curious what real outcomes this transformation is associated with. is the overall research quality better? do people ask better questions or design better studies? are more results reported in titles, abstracts, & media valid or measured? do fields move forward faster or more effectively? etc.
Wow.
Look at how rapidly preregistration has become the norm in experimental economics.

Two common findings from sleep research are that 1) short sleep durations predict worse health outcomes, and 2) people from some cultures sleep much less than those from others. Do people from cultures with short sleep durations have worse health outcomes? 🧵

Do you or anyone you know have a template/code for an e-prime experiment that integrates with a Smart Eye eye-tracker?
I just realized I may save a lot of time if one of you just happens to have any example I can borrow from. Also: any leads would be appriciated.
