Yes, in fact it’s the most obvious things which need scientific study most desperately, because what’s “obvious” today may tomorrow be “cigarettes are good for your health”. If something is obvious (and isn’t a value or opinion), that’s a red flag that you should double-check because it might be an overlooked assumption rather than an objective truth. That being said it’s not exactly “sexy” science since the result tends to be “our hypothesis was correct”. The Ig Nobel Prize has some good example of this, dumb “obvious” or “pointless” research that on further reflection makes you think.
