I haven’t done a science fact of the day lately. Work is time consuming. Don’t forget, science facts of the day are my thoughts on and descriptions of what scientists say. In other words, it’s a fact that some scientists have said it. What I write is not necessarily a fact of nature nor something I even take to be the case.
In an article at Big Think, an author describes this analysis of online dating data.
In a recent experiment, psychologists “designed a procedure to intentionally induce a placebo effect” in order to test the claims of intelligence increasing software.[1]
The study has a small sample size, but bear with me.
In the control group (people who simply thought they were participating in an experiment) there was no difference in pre and post training intelligence. In the experimental group (who were told they were training to increase their intelligence) an increase in intelligence was measured (5-10 IQ points) after only one hour of training.
