Perceived Value vs. True Value: Is There a Difference?

This is a great TED talk: Rory Sutherland makes an entertaining case for thinking more about psychology in the way we design and enhance things (and less about technology).

One example: one of the best improvements to the London Underground in ROI terms did nothing to change the trains or how they ran. Instead, it was to install displays on platforms to show passengers when the next trains were expected.

If you have a few minutes spare, it’s worth a watch.
