what sort of intelligent person believes random caller that says "your
computer is running slowly"

There are people around who aren't very intelligent. In fact some really
stupid people seem to survive to a ripe old age.

And plenty more that know so little about technology that
they dont have a clue whether their service provider can
work out if their computer is running slow or not but are
aware that a service provider can ring you and tell you
that there is a problem with the service being provided.
