If asked about their length, you will say what you know. But you still see the bottom line as longer. You have chosen to believe the measurement, but you cannot prevent System 1 from doing its thing; you cannot decide to see the lines as equal, although you know they are. To resist the illusion, there is only one thing you can do: you must learn to mistrust your impressions of the length of lines when fins are attached to them.”” [Daniel Kahneman](https://sms4smile.com/quotes/author/daniel-kahneman/) ## About This Quote This interpretation was drafted with AI assistance.
