I've known people who conduct research for money, some for prestige in the scientific community and beyond. Only a few for the sake of relieving suffrage. Most "get tired of it" due to the politics they encounter. It is hard to maintain enthusiasm when your budget is cut, because your results are not what others want to hear. Does every one of the criteria I mentioned need to be met to make a scientist, no. But I do believe that a person that tries to adhere to higher ethical principals deserves the title. In the past "Scientist" was a much honored term. The title does not inspire what it did just thirty years ago. Within recent history I have seen cases of falsified data, probes lost due to rushed programming, shuttles with crew lost due to incompetence, drugs released to the public with side effects more harmful than the disease, etc.......Where does it end? It ends with a scientist that adheres to the principals I previously covered. The degree should not be the sole identifier of a scientist. Nor the position they hold.
