Testing is a skill to learn like anything else. Teams that dogmatically apply any new practice or process without making a genuine effort to learn that thing will never extract value from it. If your team can try, fail, and learn from mistakes, you are in a mature organization. If your team gives up quickly because of fear of dogma or has no strategy for dealing with the challenges of learning new skills, it's unlikely your team will ever extract value from testing until the team culture itself changes.

IME, the problem more usually happens because someone in management read a book and thought "I know, we can change our entire development process to do this thing I just heard of and overnight my team will all become 10x developers!"

If you've got a team that is genuinely interested in improving and willing to work on new ideas to make the best use of them, both reviews and testing can obviously be very helpful. That's not really the situation I'm talking about above, though.
