How social media helps scientists get the message across

New study suggests good research pushed through social media gets more citations.

By JENNIFER-ANNE PASCOE

Analyzing the famous academic aphorism ”publish or perish” through a modern digital lens, a group of emerging ecologists and conservation scientists wanted to see whether communicating their new research discoveries through social media—primarily Twitter—eventually leads to higher citations years down the road.

Turns out, the tweets are worth the time investment.

Cargo Cult Science

RICHARD P. FEYNMAN

Some remarks on science, pseudoscience, and learning how to not fool yourself. Caltech’s 1974 commencement address.

During the Middle Ages there were all kinds of crazy ideas, such as that a piece of rhinoceros horn would increase potency. (Another crazy idea of the Middle Ages is these hats we have on today—which is too loose in my case.) Then a method was discovered for separating the ideas—which was to try one to see if it worked, and if it didn’t work, to eliminate it. This method became organized, of course, into science. And it developed very well, so that we are now in the scientific age. It is such a scientific age, in fact, that we have difficulty in understanding how­ witch doctors could ever have existed, when nothing that they proposed ever really worked—or very little of it did.
