Indeed 'one big reasons' seem very pathological for me in popular science and even some serious science. I believe we are attracted to a single fact explaining a lot: it gives some weird satisfaction, like seeing a puzzle come together; while this can work for creating a mathematical theory or explain some basic physical phenomena, it doesn't bode well when applied to complex systems or people. I get impression it happens all the time with cancer; I think the bee collapse saw some of this effect too. All this motivation for finding 'the explanation' does lead to discovering mechanisms though -- but I suppose we still need some more lucid 'integrators' to combine many effects into a strong enough causal system.
