Certainly!
I didn't say science always finds evidence in support of a hypothesis, or that all hypotheses result in repeatable results. I said
My problem (and that of most natural and physical scientists) with much social science research is that
conclusions are drawn (even begun with
) that are not supported with objective, verifiable, repeatable evidence. There are many valid research studies that show that the hypothesis was invalid, or whose results don't turn out to be repeatable. In those cases, it is determined that
the conclusion is not supported by scientific evidence. The conclusion is not considered "truth", unlike in social science where
conclusions not supported by scientific evidence are accepted as truth. That can be accepted by society, but it's not science.
Study all you want. Hypothesize all you want. But you don't have a
scientific conclusion without objectivity, verifiability, and repeatability. Observation followed by theorizing about the reasons for those observations is natural philosophy, not science. It has it's place. It's the necessary groundwork for developing hard scientific studies that verify those hypotheses. Most social sciences do the observation and hypothesizing, but not the hard science needed to actually scientifically prove those hypotheses.
That's a good example. The only verifiable, repeatable scientific conclusion that can be drawn from that data is that babies can distinguish (in some fashion) between stimuli, that is, babies behave differently faced with different stimuli. Fine. That's not exactly ground-breaking news. Where the problem comes in is when the researcher concludes
the reason the babies look longer at some things than others. Where's the hard evidence to support that conclusion? It doesn't exist. It's the researcher's philosophical speculation about the observation.
In one of the studies my baby participated in, the researchers recorded gaze time of the babies when faced with situations that were physically normal (a can continuing to roll some time after rolling down a slope) and situations that were physically abnormal (the can stopping immediately at the bottom of the slope). The conclusion was not that babies looked longer at one situation than the other. That would be the objective and repeatable conclusion.
They concluded that babies understand physics (at some level) as early as six months old. Where is the evidence that that is the reason the babies gazed longer? And where is the evidence that they
understand at six months but not three? It might be that younger babies understand just as well, but can't hold their gaze as long. Or that younger babies show their scientific understanding differently (more blinks per minute?) It might be that the babies understood the physics. It might be that it was interesting for some other reason entirely. Maybe babies recognize "what I usually see" from "what I don't usually see", regardless of it's physical truth. You can't verify or repeat that babies understand physics, yet that is the conclusion they drew. That's not a scientific conclusion, it's a philosophical construct. It's interesting, and well worth speculating about, but it's not verifiable or repeatable. All we can repeat is that babies look longer at some things than others. Why they do so is sheer speculation.
Good
research in the area would gather massive amounts of information about the different things babies look longer at, and try to classify them into groups. We could then, perhaps, improve the quality of our speculations based on a much larger collection of data. But in the end, the "why" is still speculation, a hypothesis that is as yet unproven. That doesn't stop social scientists from treating their speculative conclusion as scientific fact. And that's where we start running into trouble with psychological research.
It's not that social studies are necessarily not constructed with a hypothesis and testability. It's that the
conclusions are not supported by objective, verifiable, repeatable evidence. The "conclusions" themselves are new hypotheses, or opinions of the researcher on the reason for the results,
not scientific conclusions themselves.
It seems to me that we (as with all the other social/physical/natural scientists in the world) are going to have to agree to disagree about what is classified as science. It's a big question with a lot of egos invested in it and we are not going to resolve the issue here and now.
