It's a great phrase. And we can use it to help us think more critically.
Take shopping, for example. A shirt costs £20 in one store. But you can get it for £10 if you walk 10 minutes to another shop. Sounds like a good deal, right? But now, imagine a £500 TV is on sale for £490 at that same store 10 minutes away. Suddenly, saving £10 doesn’t seem worth the trip.
That’s the Contrast Effect in action (as explained in Rolf Dobelli’s book, The Art of Thinking Clearly). The amount saved is the same, but we see it differently based on what we're buying. If time is money, shouldn’t 10 minutes of our time be worth the same, no matter what we’re spending it on?
A lot of people and businesses fall into this trap. We don’t judge value on its own. Instead, we compare it to whatever options are in front of us. We end up justifying decisions based on comparison rather than objective value.
So next time you hear time is money, ask yourself: Am I really spending it wisely?
