The Quora Credentials bot is very inflexible, and it’s been difficult to work out how to get it to shut up.
And the credential is being rejected because the Credentials bot doesn’t think it’s helpful; not because it necessarily isn’t helpful.
In the absence of Quora publishing a Guide to getting the Credentials bot to shut the hell up consisting of useful credentials templates (because that would require Quora Inc to actually care about its users), I suggest offering an academic-looking credential. OP has tried the following phrases:
Student, Aspiring Psychologist, Aspiring scientist, Psychologist student
I’d suggest something like
BSc (Psychology), So-And-So University (year of graduation)
Or, at a minimum, a phrase longer than two words, such as
Studying developmental psychology, aiming to practice in clinical psychology
or in fact your existing other bio, OP,
Polymath, Reads a lot, science fan, student
And whatever you do, don’t use the phrase
Empirical research by Zeibura S. Kathau and myself confirms that phrase gets deprecated. 🙂
