Experience is different than authority and I don't think the parent comment was complaining that the first reply didn't have the authority to say what they did.

Experience is different than authority and I don't think the parent comment was complaining that the first reply didn't have the authority to say what they did. I assume they were saying that you shouldn't place a lot of importance on someone with all of three seconds of experience in this problem. Especially when compared to researchers who have been thinking about it for decades. There are probably good reasons why they think boiling the problem down to so few dimensions is useful that I don't fully understand because I have literally no experience in psychology.
