Is it possible to survive as a researcher being a dispassionate person?
The &quot;passion&quot; thing is a myth and a shoddy cliche.
Your true feelings need not have any effect on your career.  You just need to do the job.  In academia, there is lots of competition, so &quot;doing the job&quot; means doing it very well - among the best in the world.  But this requires actions, not feelings.
It can be handy to have the skill of making others believe you have certain emotions, though.
If you dislike academia, don't be an academic.  Especially don't teach if you dislike it.  There are better paying and easier jobs that are no more dislikable than teaching, but where you cannot harm students.
