as for me it's not about the psychology. basses, as stated, mostly get amplified clean. this IMO is where active electronics (OB preamp/ pickups) excel in. the other factor being the frequency in use; the bass' low end sounds very receptive with active circuitry, not the case with guitars which operate on a different aural spectrum.
Sorry to burst your bubble, but that's not true at all, completely untrue. A strat pickup is not different from a J bass pickup, the magnet strengths are not different, the wire guage is not different and the number of windings is not different. For all intents and purposes you could use a strat pickup in a J bass and a J bass pickup on a strat on one string and there would not be much difference other than the polepiece spacing. If you use a bar magnet design you could in practice use a strat pickup for a bass and a j bass pickup for a strat.
The tonal spectrum on the instrument is the same, the natural cut off for a normal electric guitar is somewhere in the region of 75hz and of course the basses go lower because of the thicker strings and the tuning. But electronically there is not much that is different on the instrument. Granted some pickup designers alter resonance peaks here and there but based on the wire gauge, windings, and magnets these shifts are not radical but a shift in the mid range. All pickups have slight variances in resonance peaks but they are not wildly different.
The difference in tonal performance occurs completely after the instrument not on it. You could use a bass guitar and string with long stirngs the gauges of say 0.10 to 0.46 and you would get a piccolo bass, except that it is effectively a long scale guitar. Brian Bromberg does this and runs it through a guitar rig and sounds like any other guitarist. You could also string a 25" scale guitar with bass strings, say 0.40 to 0.105 and it would sound like a bass.
All the tonal spectrum differences occur after the instrument. You could put a buffer preamp on a strat and use the same rig and it would still sound like a guitar. Yngwie Malmsteen's preamp boost is a buffer preamp on the floor with some gain, and frankly he could put it in the his strat, but the general perception is that you don't want to do that.... Many guitarists will play through a multi-efx floor console like a Boss or digitech or whatever but if you put in on the instrument, they cry foul.
