Comment On Science, Actuaries, and FUD (Score 4, Insightful) 139
"Science" lacks a robust definition, but clearly the OP's definition is overly simplistic and narrow. Stephen Hawking has a lecture somewhere (found it: http://www.hawking.org.uk/the-origin-of-the-universe.html) where he talks about the idea of the "positivist" approach defined on the ability to predict outcomes, and I like to apply that definition to Science (Hawking doesn't, directly, but it's sort of an underlying theme). That is, Science becomes the observation and experimentation required to form predictions or cause changes in predicted outcomes.
So Social Science can be a science in so far as it actually informs usefully on how people will behave or provides useful ways to affect and improve the behavior or state of society's future. Computer science is a science insofar as it is required to make computers function as expected (as predicted) -- if you want something to perform faster, you must do the research and experimentation to cause the outcome to be faster. Even archaeology can be a science by this definition in that discoveries are added to a general model of the past that predicted all sorts of things -- ancient society's behavior, glaciation, geological events... "predict" may be a stretch there (except when archaeological finds help predict the future), but in this case the method of building a model of how the world worked based on observation to describe and generalize behavior (of the earth, of ancient religions, or what have you) is a form of prediction; it's just after the fact.
Data Science is very much science in this form; the job of a data scientist is almost universally to predict what the data will say about the future given what it has said in the past. This is invaluable to businesses and while the name may fall into disfavor, in the same way "actuary" which means something very similar already has, the abuse in this article is unwarranted, unfounded, and inaccurate. I will only agree that many who sport the "Data Science" moniker may not actually be doing science by any definition, but that's the individual's fault, not the concept's.
