How much credence should we give Ariely’s Predictably Irrational?

I’ve seen this book recommended repeatedly in threads about getting into economics, and as a staple in the subs official reading list and I’m genuinely puzzled by it. A few concerns:

On the empirics: A substantial portion of Ariely’s experimental findings have failed to replicate. More seriously, there have been credible allegations from within his own research group of data fabrication in at least some of his studies. At what point does a pop-economics book with this track record stop being a useful introduction to the field?

On the conceptual framing: Even setting aside the data issues, Ariely’s use of “irrational” seems to do a lot of unexamined work. In the opening chapter he describes nurses who prefer to remove bandages slowly as irrational, because their preference differs from his. But heterogeneous preferences aren’t irrationality in my understanding; they’re more akin to the starting point of all exchange in economics. Is this framing just a popularization shortcut, a purposefully sensationalized rhetoric to sell copies, or does it reflect a deeper confusion about what behavioral economics is actually claiming?

Curious whether people here still think the book has pedagogical value despite these issues, or whether its continued appearance on reading lists is just inertia.
