> I am curious whether this works in the opposite direction. Does this also imply that if people take a long time to decide, then the options are roughly equal? I can disprove the hypothesis above with a counterexample: Which is the better deal if you're buying gasoline? 500 liters for ¥10000, or 100 US gallons for US$500? The difference is huge. There's almost a factor of 10 difference in price per unit volume. But you have to spend significant time to figure out which is better. And it's easy to make the problem harder. So the answer to the OP's question is no; if people take a long time to decide it doesn't necessarily mean that the options are roughly equal.
