What do we mean by 'common sense'
We are talking at cross purposes. I wouldn't have invested hundreds - thousands of hours here on the HUG if I believed that science was as simple as the application of a little common sense.

One serious issue with the internet is that it creates the instant expert but it takes real effort and (that word again) 'common sense' to 'smell' an opinion that just doesn't seem to fit with ones real-life experience outside audio. Science is science and it must be consistent throughout the universe, so if you read that an aerosol spray dusted over your equipment will transform the sound of your system, does that square with your observational experience in the real world outside the listening environment? What other example can you draw on of the transformational power of an aerosol except perhaps in a health spa? If it does, then for you the magic aerosol is a must-have regardless of what others say. If it doesn't then your 'common sense' rejects the very notion of sonic aerosols.
It's not the arrival at the technical truth by the application of common sense we are stumbling over - that couldn't be expected of any non-specialist in a science field - it is the rejection of what are exceedingly unlikely to be technical truths by the application of (that word again) common sense. That's quite a substantial difference of emphasis.
Please remember one thing that may not be obvious. When I reply or comment here, I am not just attending to the specific issue for the specific respondent, I am trying to present a broader, simplistic, more universally applicable response (including this one) that will save me having to re-visit the issue again as I am not able to devote routine time here.
I hope that completely resolves any misunderstanding about common sense.
P.S. The acid test of my suggestion that it is the failure to apply common sense to compare and contrast with real-world experiences that leads us up the garden path would be to chose a subject we may mutually know little or nothing about. Plenty of choice for me: wine? Or nuclear physics? Or fish husbandry? Construction of the PostScript language perhaps %%? Let's stick to wine. We set off with an objective to find a really great wine, and we start mixing with wine experts. At first, we absorb knowledge like a sponge: it's all new and exciting, but we reach a point where contradictions and doubts start to creep in. One says that his flavour is certainly due to the unusual soils in his vineyard irrigated from a clean stream. Another says that, no, the secret of his great wine is that of the full moon shining on the bald heads of the peasant workers as they pick the grapes after midnight. A wonderful romantic story! You can see it in your mind's eye! But really, a little application of common sense surely tells you - even if you know absolutely nothing about irrigation or grapes - that the moonshine tale is nothing more than advertising puff. Or so it should. But that's not how audio works.
