I think its the nature of the thing. Some fields are easy to 'big picture' - like physics (apart from quantum-level?) or biology. If they relate to everyday experience then that is surely easier. Chemistry often deals with the everyday, of course - drugs, paint,fuels, cooking even. However it can also deal with very obscure reactions where the details are entirely technical. For example, there are whole papers dedicated to "this is the detailed series of steps we found to make this obscure chemical (X) that is difficult to make". That could be summarised as just "we made X!" - not super interesting, by itself...
