Noted, but they still are pretty accepted in mainstream economics (nobel prize in economics in 2002).
Also of course, they're not the only ones doing behavioral economics [1]:
> Imperfect information is core to modern econ; theories showing how imperfect information can cause markets to break down received a Nobel 20 years ago. Perfect rationality has been successfully challenged by behavioral economics for decades, and received Nobels in 2002, 2013, and 2017.
Just FYI, both Kahneman and Tversky were psychologists, not economists.
