Laura,
for an interesting take on relaibility you could try reading Stephen Dawkins
"Unweaving the Rainbow" (from all good book shops). Dawkins area of interest
are in genetics and this text discusses amongst other things how evolution
may have programmed man (and other creatures) to look for patterns in what we
do and see. I think he suggests a valid theory of why errors in perception
may occur. This could be a nice background element to your discussion maybe.
Good luck
