The more choices we have, the more likely we are to make a sub-optimal choice, and therefore the more likely we are to be unhappy with our lot.

According to this fashionable theory...

If I have to choose between, say, black and white, I am very likely to make the right choice.

If I have to choose between black, white, red, yellow, blue, green, orange, purple, grey, cream and magenta, I am less likely to make the right choice. (Not brown. No one would choose brown).

And if I have the choose between every single colour anywhere, then the chances of getting the choice exactly right are tiny.

The more colours, the greater the likelihood of picking the wrong one.

Knowing I haven't got the best is depressing. Therefore, the more choice I have the more likely it is that a depressing outcome will result (although 'greater likelihood of depressing' is not the same as 'more depressing').

Thus, voila, this will only make me sad.

Though one would not have thought so.
