In an experiment involving rats, if they wanted food, they had to choose between different paths to get to it. There was a direct path, and another maze-like path with branches. Both paths would lead to the same food, so if the rats wanted food, they'd take the direct path. However, many of them preferred the other route.

Similarly, in experiments with monkeys and pigeons, if offered to press a single button or multiple buttons to get food, the majority prefer pressing multiple buttons.

And humans are very much the same. When given chips to use at a casino, people were told they could use them at a table with one roulette wheel, or another with two where they could choose. Despite the wheels being the same, people preferred the second table.

So what does this mean?
