Fun fact: because we rarely have a complete set of information about anything around us, but our brains still try to form conclusions on what’s available, much of what we think about the world contains a cognitive bias. Curious? Jason Kottke runs through the concept and provides some great links. Be prepared to doubt everything you know.
Though scientists are widely accepted to be coldly analytical and impartial, their hopes and expectations can, if not correctly addressed, create a bias, interpreting results from data which do not exist. To combat this bias, a small team at the LIGO gravitational wave telescope was tasked with secretly inserting false data into the observations. It kept everybody on their toes, and ended up streamlining things in the process.
