To expand on my earlier post, this depends on what wrong means. If we think
about linear regression, the coefficients do represent the difference in means
(dummies), or the slope of the best fitting linear line. In that respect the
coefficients aren't wrong. These coefficients just may not be the same as
causal effects. So if you want to make the (very demanding) condition that the
coefficients are also causal, then they may be wrong.
