If you have an exam, or an IQ test (do they still have those?) coming up, then there’s a psychologist who has some words of advice for you…avoid looking at anything red just beforehand. According to a study, even a short perception of red initiates avoidance behaviour and sends test scores plummeting.

This suggests a tactic for improving your relative score…

Using green-colored glasses for self-protection, sit at the front of the hall & mess with the other test-takers’ cortical activation levels by wearing a bright red shirt.

…just kidding…that would be unethical, wouldn’t it?
