If you’ve ever been close enough to lightning when it strikes you may be familiar with the startling high frequency thunderclap or crack it makes. But the high frequency soundwaves of the clap are attenuated by their travel through the air away from the source so that from a kilometre or so away all you hear is the growling of the thunder rumbling away as it clatters and rebounds off everywhere it hits. I learned about this from Randall Munroe’s fun book How to: Absurd scientific advice for common real-world problems.…If you’ve ever been close enough to lightning when it strikes you may be familiar with the startling high frequency thunderclap or crack it makes.

Sometimes we’re smart enough to know that we’ll have trouble doing something we want to get done. That might be going to the gym, finishing that essay instead of goofing around, quitting smoking, doing your taxes, or, if you happen to be Odysseus, listening to the sirens’ song without going crazy and diving in the water or driving your boat to be crashed on to the rocks. In these cases, you can try a commitment device: a voluntary restriction to help maintain our future self-control. In Odysseus’s case he instructed his men to fill their ears with wax and to bind him the mast and told them if he asked them to let him go then they were to bind him tighter. In this way, he managed to listen to the sirens’ song without ending up at the bottom of the sea. Other commitment device’s may be more mundane, such as publicly announcing to your friends that you’re going to do something, paying a bunch of money to sign up for something upfront, or handing a $20 bill to a friend with instructions not to give it back until you’ve done what you’re supposed to. Here are some nice examples of commitment devices.…Sometimes we’re smart enough to know that we’ll have trouble doing something we want to get done.

You have to drop off 2 things after school, get to the shops and back home — which route should you take? You drive an Amazon delivery van and you have 145 parcels to deliver across London — what’s the most efficient route? It’s pretty clear that for situations like the first one, with fewer stops, assuming you know travel distances or travel times, you could figure out the best route by trying out the different combinations until you hit on the shortest. The trouble is as you keep adding extra stops it doesn’t get just a little bit harder — instead the difficulty continues to increase along with the time it will take to find an answer. Figuring out the shortest route to visit all the stops and return back home is known as the travelling salesman problem. It’s a problem formulated over 150 years ago that still has relevance and interest today whether it’s for delivering parcels, stocking shelves or soldering transistors.…You have to drop off 2 things after school, get to the shops and back home — which route should you take?

The more transparent your workplace the less transparent your employees. In an age of trackers, wearables, online monitoring, workplace chat and always-on devices it turns out that not only does a more transparent workplace actually drive people to more secretive behaviours, but that adding a little more privacy actually may improve productivity also. As Ethan Bernstein says: Very simply, the transparency paradox is the idea that increasingly transparent, open, observable workplaces can create less transparent employees. See Harvard prof Ethan Bernstein’s The Transparency Paradox study (pdf) or I learned about it from the Freakonomics podcast: Yes, the Open Office Is Terrible — But It Doesn’t Have to Be.…The more transparent your workplace the less transparent your employees.

In 2016 the British Government had plans to launch a new polar research vessel. To decide on a name for it, they put it out to a public vote. Despite a number of serious, meaningful or historic names suggested, like Shackleton and Endeavour, one name put forward, Boaty McBoatface, quickly overwhelmed all the other options put together. It turns out this is not limited to the British sense of humour, and people will vote for a joke candidate because it’s fun and subversive, and people want to see what will happen if it wins. This NYT article by Katie Rogers has some other fun examples of competitions going ‘wrong’, such as an attempt to name a bridge 'Chuck Norris’ and selecting a school for the deaf as a concert location: What you get when you let the Internet decide. I learned about the Boaty McBoatface effect from Dr Roger Miles on the Human Risk podcast. Also see Conduct Risk Management: A behavioural approach by Dr Roger Miles.…In 2016 the British Government had plans to launch a new polar research vessel.

The data prison is the default table where the bars of the cells crowd out your data with non-data-ink and lock your data into a prison. When data is locked into cells, their relationships with other data are harder to see, and the reader has to work harder to learn from your table. When making a table of data, consider if, by adjusting spacing and alignment, you can make the columns or rows clear enough as they are without the prison bars. And look for opportunities to remove the visual noise to let your data and the relationships between them shine out. The data prison is a concept from Edward Tufte.
