I really don't get you stance. Of course, you can make more fine-grained distinctions and that's fine. You can claim that medical doctors act as medical scientists when they conduct studies and as doctors (consultants) in their practice with patients. But that doesn't mean the value judgments aren't part of the science.

If a seismologist has evidence that an earthquake is likely to occur in a certain area, should they not warn the public about it? I would say they clearly should, and any other view about this seems bizarre to me. I find it equally implausible to not call a seismologist who warns about an impending earthquake a scientist. They're a geophysicist or geologist. Or take an astronomer warning about a possible collision of a meteor with Earth -- astronomy is a science, so why would that person not be called a scientist?

There is a an array of scientific disciplines for whom consulting (in your sense of the word) is a frequent, though not primary part of their activity, and we certainly still call them scientists. Material science, vulcanology, epidemiology, seismology, meteorology, biology, climate science, economics,... basically any science that involves the study of processes that might have important consequences for mankind.

Oh well. Its mine, not yours, so who cares?

Scientists seek to gain the understanding, but generally taking that understanding and turning it into what a society is concerned with is left for other disciplines (e.g. engineering). Generally, scientists don't also have the social understanding of the application of science. It is not impossible for them to. Humans can do many things. But it is generally impractical given that there is only so much time in the day. Having the beat of the social ground is a full-time job in and of itself.

I know HN leans towards DIY and struggle to think that they can't do it all, but out there in the real world there is much greater division of labour. A random scientist's warning holds no more weight than a hobo on the street's warning after said hobo has read the same research.

I don't disagree with much you've said, the only thing that bothered me after having worked for 20 years at university is the lack of realism of your views about scientific practice. Scientists have to deal with politics a lot, and if it's just with fundraising schemes that often explicitly demand social relevance of the research. That's particularly the reality of disciplines that are extremely relevant for society such as climate science. Of course, they need to assess to some extent whether the consequences of climate change are good or bad for society. This is a no-brainer, if you'd bother to stop and think about how they would structure and organize their research and get funding for it.

You must be joking, and I wish people would do that less often when talking about serious topics.

What delineates a scientist from a crackpot?

The Internet gives equal voice to both, but the latter will drown out the former until people stop listening altogether.

The biggest and maybe only relevant difference is that one of them works evidence-based and the other one doesn't.
