Not necessarily if it simultaneously produced research saying that cigarettes are good for your lungs.
Nah. Eventually some folks would decide enter the lung-doctoring profession because their parents had died of lung cancer and they actually wanted to cure it. People are not predictably 100% short-sighted and mercenary; the Prisoner's Dilemma is not the "Prisoner's Stupid Question – Obviously Everyone Defects All The Time."
Just giving a short table-summary of an article by James Shanteau on which areas and tasks experts developed a good intuition - and which ones they didn't. Though the article is old, the results seem to be in agreement with more recent summaries, such as Kahneman and Klein's. The heart of the article was a decomposition of characteristics (for professions and for tasks within those professions) where we would expert experts to develop good performance:
Static stimuli
Decisions about things
Experts agree on stimuli
More predictable problems
Some errors expected
Repetitive tasks
Feedback available
Objective analysis available
Problem decomposable
Decision aids common
Dynamic (changeable) stimuli
Decisions about behavior
Experts disagree on stimuli
Less predictable problems
Few errors expected
Unique tasks
Feedback unavailable
Subjective analysis only
Problem not decomposable
Decision aids rare
I do feel that this may go some way to explaining the expert's performance here.
