When highly qualified experts can sometimes get things very wrong you might be forgiven for thinking that the answer is yet more study and training. An in the well known case of  a carbon trading expert in 2019 who “couldn’t remember” if he had passed any A-levels and hadn’t read any books on the subject you would probably be right.

But academic qualifications by themselves are not everything, the important issue is whether an expert has relevant qualification and experience.
