On common sense.

Thanks, very interesting...

Glad you thought so!

...common sense is not a good guide in digital is it?

Actually, it depends on who the "sense" is "common" to!

A prime example is Equivalence. One of the principles of Equivalence, that it is the total amount of light that falls on the sensor (photons) rather than the density of the light that falls on the sensor (exposure -- photons / mm²) that is the primary measure, makes complete sense to me, and it is surprising how many do not understand such a simple principle.

Likewise, it makes perfect sense to me that more pixels covering the same portion of a photo than fewer pixels would collect the same amount of light, but simply sample the scene with a finer level of detail, resulting in a photo with greater IQ. Furthermore, I don't see why so many think smaller pixels would be less efficient than larger pixels -- would four one quart containers hold less water than a single gallon container?
