She: *sends photo of woman*
She: What do you think? Is this pretty?
Me: I guess. She has dead eyes, though. Like she's being forced into taking the photo, by financial circumstances or other sinister powers. Maybe sedated to get through the working day or--
She: The dress. I mean the dress.
Me: Oh.😁

Sometimes even a huge amount of feedback just doesn't make a dent in overconfidence — as demonstrated by this new study involving chess players: www.bps.org.uk/research-dig...

Overconfidence can thrive even with detailed, continuous feedback | BPS

A new study looks at overconfidence in chess players, and suggests that efforts to reduce it in everyday life via feedback can still fall flat.

Assigning agency to techniques seems to me to be an attempt to avoid responsibility. “I used TDD & got poorly designed/unreliable/hard to understand code—not my fault.”
