I recently installed a big telly in the foyer of this building. It shows
a full screen image for 20secs, randomly chosen from a selection of
around 90. But folk are commenting that it's biased so they keep seeing
the same picture. I've noticed it too - walk past the thing several
times during the day and the same photo will invariably be showing.

Except of course, it's not. When I ask people which photo they keep
seeing, they all come up with different ones.

So, then, what's supplying the randomness in this case? Are you setting up
the whole sequence in advance, or making a new `random' choice every 20
seconds? You could set up a good random sequence by printing out numbers
1-90 on slips of paper and wandering around having people pull them out of
a box. Otherwise, it's always going to be biased by something. In this
case, I can't help wondering if `time of day' is playing a part here.
