Study (N=16) finds AI (Cursor/Claude) slows development (europe.pub)

Before starting tasks, developers forecast that allowing AI will reduce completion time by 24%. After completing the study, developers estimate that allowing AI reduced completion time by 20%. Surprisingly, we find that allowing AI actually increases completion time by 19%

N = 16

N=16 developers

You’re acting like this is a gotcha when it’s actually probably the most rigorous study of AI tool productivity change to date.

[–] FizzyOrange@programming.dev 1 points 2 days ago

It definitely is... But it's possible to be the most rigorous study and also not really prove anything. Proving this sort of stuff is ridiculously hard and expensive. We don't have proofs for even the most obvious things in programming, like that comments and good variable naming help comprehension. Sometimes studies even find the opposite.
