Our expert says:
There's little scientific background to the validity or such tests in these situations. As Purple explains it, these practices are based on some really lousy logic.
Right brain / left brain stuff is largely hokum, and career coaches, like Life Coaches are largely self-qualified people who love being paid for their amateur opinions.
I like Purple's suggestion that you ask each time for feedback on the results of those tests, so you can find out what's not working there.
