it's exceedingly difficult to fairly aggregate voter preferences, but all current voting systems seem to reduce all that complexity down to a singular choice in the overwhelming majority of cases. that's a shitload of information discarded, to put it crassly. the neat thing about conjoint is that it multiplexes the choice-making (when designed well), so that the choice burden scales reasonably while also better representing collective choice. nothing is going to be perfect, but conjoint could potentially be better than all current systems, probably by an order of magnitude or more. it's relatively complicated, so yes, 'experts' (i disdain this term, frankly) could in theory manipulate the system, but transparency of voting data (just like now) and survey design (the more likely bias vector) would make that difficult. transparency would allow competing independent journalists, academics/researchers, political analysts, etc. to weigh in and balance out biases (not perfectly of course), as well as verify results.
