The simple fact that the start of something, pretty much anything, means we’re more likely to try something new. Be it your birthday, your next house, a new day or a new country, these turn out to be great mental triggers for us to get started.

For more, you could do much worse than listen to Katherine Milkman, an assistant professor at The Wharton School of the University of Pennsylvania, on the Freaknomics podcast: When Willpower Isn’t Enough.

The fresh start effect

We love it more if we made it. Or, more scientifically perhaps, the IKEA effect is ‘the increase in valuation of self-made products,’ when we have put more effort into it. 

Turns out, if we’ve put effort in ourselves we’re also likely to think that others will like it even more just as we do—usually not the case. But for us at least, more effort = more love.

Watch Dan Ariely do a great job explaining some experiments that lead to this conclusion, or read the full paper, The “IKEA effect”: When Labor Leads to Love (pdf), Norton, Mochon, Ariely HBS working paper, 2011.

Dan points out that kids are the ultimate expression of the IKEA effect: they’re very hard, they don’t come with instructions and they take a lot of effort.

Also see The Betty Crocker Effect, or ‘the egg theory.’

The IKEA effect

How do you remember which are stalactites and stalagmites in a cave? And how to spell them?

The key to getting the whole thing the right way round in my mind is to remember that you need to cling tight (tite) to the ceiling. Once that’s established, you have a letter C in stactite that fits cling and ceiling. And stalagmites, with its cheeky G, naturally then is the other one which would grow on the ground. Sorted?
