A/B testing
A/B testing is the practice of tossing variations of headlines or button colors into two buckets, leaving the outcome to the coin toss known as a computer. Slight tweaks spawn a carnival of madness where 0.1% differences in click-through rates become existential battles. In the end, both versions exonerate and condemn each other in equal measure, leaving ownership of failure ambiguous. Psychologists call it behavior experimentation; executives call it a magical incantation that drains budgets in the name of optimization.
