the advertised article has the boring title
Looking on the (B)right Side of Life: Cognitive Ability and Miscalibrated Financial Expectations
https://journals.sagepub.com/doi/10.1177/01461672231209400
this was very specifically measuring the development of the family household finances vs actual development, quoted below.
it escapes me how this leads to the generalization that optimism is a sign of stupidity (translation from academesian to plain English by me).
as a reality check, innovation is driven by optimism. this whole site here is thriving because of optimism. smart, intelligent optimism.
the original article has a much more nuance
Financial expectations were measured via responses to the following question asked in all 12 Waves of USoc:
“Looking ahead, how do you think you will be financially a year from now, will you be. . .
1. Better off
2. Worse off than you are now
3. or about the same?”
