Here's some more evidence that choice can be bad for us, from Bruno Frey and colleagues:
In many countries, TV viewers have access to more and more TV channels. We study whether people can cope with this and watch the amount of TV they find optimal for themselves or whether they are prone to over-consumption. We find that heavy TV viewers do not benefit, but instead report lower life satisfaction when exposed to more TV channels.
The effect is big. For the 10% of people who watch most TV, relative to what you'd expect from their demographic features, moving from 3 to 10 TV channels depresses well-being by one-third of the effect of getting divorced.
The mechanism here is very different from the "paradox of choice" described by Barry Schwartz. The problem isn't that choice is inherently bad. It's that more choice causes akratic people to over-consume, which they later regret.
