How to persuade someone to not pursue a PhD just because they failed to find a job? I have a friend who is unable to find a job in the industry. He's a fresh university graduate. He's now applying for a PhD position because he's found a supervisor. I have every reason to suspect that he wouldn't enjoy the degree because:


He's very good at memorizing text-books and past-exams, but never able to come up with a solution independently.
He doesn't enjoy reading unless it's required for exams.
He plays and socializes a lot.
He came up with this idea after failing some job interviews.


I think he just wants to go back to university because job interviews are tough.
How about introducing your friend to PhD comics. At least someone who has read those and still goes for a PhD cannot say they haven't be warned.
