The Bad Science Reporting Effect

The Chronicle of Higher Education:

The press coverage of the so-called “QWERTY effect” in early March left me somewhat worried that it is so easy to publish bad science, but absolutely appalled at the state of science reporting.

The alleged effect is that average scores on reported positivity or happiness associations are slightly higher for words having more letters from the right-hand side of the keyboard.

He then replicated the effect on a new data set. “It’s comforting,” he says, “to see apparent confirmation … in an independently-collected data set, with a similar adjusted multiple r2 of 0.0013.
