The importance/urgency matrix

James Clear (Jamesclear.com) has a host of ways to help make sure you focus on the importants like starting every day with the most important activities, and ruthless focus. I spent a year organising my to-do list in these boxes and it was striking just how long the important not urgents keep getting moved on to the next list. Part of the secret there is to break them down to startable tasks rather than big projects. FWIW I don’t actually recommend the really concrete action of organising the to-do list in the quadrants. More being cognizant of what type each task is. But it may help for a while. This is also known as the Eisenhower Matrix.

Prices written smaller seem more affordable example

Prices written smaller seem more affordable

Unfortunately, there are studies to show that this is generally true, and prices written smaller are seen as more affordable than those written larger. What with decoy prices, anchoring, the age-old susceptibility to 99s and a host of other biases, we’re at the mercy of many factors when it comes to trying to make vaguely rational pricing decisions. For plenty more see William Poundstone’s, Priceless: The Myth of Fair Value (and how to Take Advantage of It), Scribe, 2010.

The decoy price

The technique of adding a significantly more expensive option in order to instantly make the other options look reasonable by comparison. These kinds of manipulations have been shown to be scarily effective. For example: Pricing decoys are another way retailers get you to part with more money than you planned on. In his book Predictably Irrational, behavioural economist and professor Dan Ariely demonstrates how a large magazine successfully employed a strategy called the “decoy effect” to increase revenue from subscription sales. Prospective subscribers were given three choices: 1.       Web-only subscription for $59 2.       Print-only subscription for $125 3.       Web + print subscription for $125 At first glance, the middle price point appears to be superfluous. Why would anyone buy a print-only subscription for $125 if they could get a web and print for the same price? Ariely tested the price points with MIT students and found that 16% of students chose option 1 and 84% chose option 3; not surprisingly, none chose option 2. Then Ariely did something really interesting; on the assumption that having a decoy price (option 2) was influencing people’s choices, he removed the decoy and retested the price points. This time, the subscription choices were as follows: 1.       Web-only subscription for $59 2.       Web + print subscription for $125 With the decoy removed, the option that had previously been the most popular – the more expensive print + online access subscription – suddenly became the least popular choice. Only 32% of those surveyed chose the more expensive option, with 68% selecting the online-only subscription. Clearly the middle price point wasn’t superfluous; it was smart marketing that made option 3 look more attractive to subscribers.

What’s the difference between mandarins, clementines, satsumas and tangerines?

I’ll understand if this hasn’t been a burning question for you. But I’ve always struggled to identify correctly when one is put in front of me. Turns out, after sleuthing, they do have separating characteristics along, colour, the tightness of skin and the amount of seeds. I had to go 3D, but I think this should allow you to identify the next small orangey thing that you eat. For the record: Mandarin Has seeds, loose skin and is orange Clementine Seedless, tight skin and orangey-red in colour Satsuma Seedless, loose skin and orange Tangerine Has seeds, loose skin and is orangey-red PS I promise no more mandarin-related sketchplanations in a hurry

Origins of mandarins world map: including Tangerine from Tangiers, Morocco, Mandarin from China, Clementine from Oman and Satsuma from Japan

Origins of mandarins

From various sources I have learned that mandarins are the original, from China, and were rather fancy and therefore only suitable for high society, which included mandarins (bureaucrats). Satsumas are a type of mandarin cultivated in the Japanese district of Satsuma. Clementines are named after Father Clément Rodier who may have cultivated the variety himself. And tangerines are so named as being from Tangiers in Morocco, one of the places where mandarins were first imported into Europe. Simple.
