Angela Lansbury has passed at the age of 96. Best known for playing Jessica Fletcher on Murder She Wrote, her film and Broadway career began decades earlier. Robbie Coltrane (Hagrid of Harry Potter fame) has passed at the age of 72. I’m not trying to sound superstitious but it seems like these things usually come in threes. That’s probably a good example of confirmation bias. If another celebrity passes away in the next couple of days I’ll be like “See, comes in threes.” Confirmation bias interprets new events in a way the confirms what you already believe. It may also be perception bias, which is hopefully just what it sounds like.
