All maps involve decisions. Whenever you compress real life onto something smaller and less detailed you have to choose what to keep in and what to leave out. And in the case of printing a map of the Earth, you have to figure out how to get something that is curved onto something that is flat, and this involves trade-offs and decisions as well. 3 dimensional space just doesn’t flatten to 2 dimensional paper without choices.

In 1569 Gerardus Mercator created a map that brilliantly solved a pressing problem — that of being able to follow a straight line while sailing and it correspond to a straight line on the map. His map also did a good job of preserving the shape of countries. But to do this you have to stretch the areas at the top and bottom of the Earth. Because most of the land on Earth is in the Northern hemisphere, and because that land is generally further north than the land in the southern hemisphere is south, it has the effect of enlarging Northern countries such as Europe, the US and Canada, Scandinavia and Russia as compared to countries closer to the equator and in the Southern hemisphere.

Most world maps you see are still similar to Mercator’s projection. In fact Google Maps desktop used it until just recently. It could well be that this distorts our worldview by emphasizing Northern countries in size and therefore importance. When I see a more size accurate Gall-Peters projection I have to say it’s hard to argue.

The Mercator projection

These are a super useful trick to increase the chances of action, be it your own others. Essentially, a vague intention of “I plan to do that,” is much less likely to be followed-through on than if you get specific. It takes out the ambiguity of when and where you’ll do something because that’s already decided. For example, asking voters simple questions like how they’ll get to the polling station has been shown to increase turnout on the day. You can use this to your own advantage too — get specific with yourself to help you get things done, be it how and when you’ll workout, or when you’ll study or whatever.

Here’s a simple template for implementation intentions you could try:

I learned this, and many more tips, from James Clear’s book Atomic Habits, all about how to create good habits and break ones.

Implementation intentions

Coined after the French philosopher Denis Diderot’s remarkably titled essay “Regrets on Parting with My Old Dressing Gown”.

The gist of the effect is that we generally surround ourselves with objects that fit our current sense of identity. If we get something that doesn’t fit that identity we may find ourselves replacing the rest to match the new identity.

Poor Diderot was given a fancy new dressing gown and ended up replacing most of his possessions and ultimately living in poverty, to paraphrase a little.

The Diderot Effect was introduced by Grant McCracken, and I learned about it, once again, from Atomic Habits. Diderot also played a key role in the development of the encyclopedia as I learned from Seth Godin’s podcast, Akimbo,
