A person who thinks they are good at optimizing their electronics, computers and other equipment, but suffer severely from confirmation
bias. Bientists "buy into" ridiculous, half-
baked and often overkill solutions usually out of a combination of impatience and arrogance. Rather than doing any verifiable research or empirical experimentation, they base their techniques on correlations, isolated incidents and things they
read once on a forum, usually posted by other bientists. If a confirmation bientists finds another confirmation bientist with the same ideas, their
ignorance is locked in for life. See also: bientist.
