Do you need a PhD after your name to be a scientist?
In theory, the acheivement of a PhD implies that one has a formal eduction, particularly with respect to the scientific method, and one can conducted some independent and original research that contributes to the advancement of the field or branch of science in which one was awarded the PhD.
Agreed. Real world experience counts. I also know people who push the envelope of knoweldge and experience as would be expected from any PhD, but they only have baccalaureate or master's degrees.How about one's education in the real world though? People with BAs and MAs who have worked for years in industry get their education from working on the job. I know some people with just BAs with 30 years experience who are incredible at science and know more than freshly minted PhDs that just got out of grad school.
There are many "scientists" who don't have a Ph.D. As long as you are practicing in that profession, you are a scientist.
