What is Optimism bias example explained: A stunt rider overestimates their chance of leaping a canyon thanks to optimism bias. Various onlookers gasp. "Huh" says the rider

Optimism bias

Optimism bias is believing things will turn out well despite past evidence or circumstances. It can be extremely helpful. It allows us to attempt things that many may deem impossible. It probably helps motivate entrepreneurs even when everyone doubts them. Optimists are often healthier and happier. But it can also undermine us. We might overestimate our chances of success because of what we want to happen rather than what's likely to happen. We may feel pressure from others to give a rosier outlook — like when you might underestimate a timeline when speaking with your boss. We might want others to succeed, or they may be paying us money and hoping for good news. We probably think we'll get more done next week. We probably think we'll be more disciplined than we will be. We might think that this time it'll be different or that everyone can't be wrong. Or we may be just discounting evidence without realising it. May your optimism be well-founded.

Examples of a ghost grid: a lightly dotted grid, and a grid of ghostly houses so that extension options can clearly be seen

Ghost grid

A ghost grid is a guide for organising thoughts, information and sketches, that doesn't compete with content. Content itself can also be the ghost grid to highlight changes and help draw comparisons — as when you might sketch options for extending a house or designing a garden. A grid is useful for structure and creation but needs to fade back from content or disappear when no longer needed. Like freeing data from its data prison, a ghost grid emphasises content and information without non-data-ink taking attention. I learned the term ghost grid from Edward Tufte's Seeing with Fresh Eyes: Meaning, Space, Data, Truth. I rarely buy other notebooks for work than a dot grid, preferably in a funky colour. Some of my favourites: Leuchtterm dot grid hardcover, Moleskine dot grid softcover, Moo soft cover dotted journals

What are the NATO phonetic alphabet words: helping two pilots correctly identify Y I V B D T which is easily misheard

Phonetic alphabet

How do you avoid confusion when spelling things out verbally, particularly when the sound isn't clear or there may be background noise? So, for example, something like Y I V B D T doesn't unintentionally get heard as Y Y B P D D. Or perhaps as I Y P V T D. A lot of letters sound similar. A phonetic alphabet, or spelling alphabet, is a way to ensure all letters are unambiguously heard correctly by using words starting with each letter. The set of words was chosen from 1,000s of tests, including real-life ones, to maximise clarity and avoid overlapping sounds with other letters that might cause mix-ups. When written out they include deliberate misspellings Alfa and Juliett to avoid misinterpretation. The NATO phonetic alphabet is a standard one, but there are other variations.

A parent and child entering an immaculate living room with perfectly behaved children unwisely find themselves comparing with their own chaotic house.

Front of house, back of house

Don't compare your back-of-house with others' front-of-house. Usually, we only see others' front-of-house, and because we know all about our own house it's easy to find ourselves comparing how we're doing in the back with how others are doing in the front. Often a recipe for unhappiness. I remember wondering how a friend was so calm before their first child. They said, "I'm like a duck, calm on the surface, but underneath my legs are kicking like crazy." The truth is we don't know how others are doing so best not be comparing at all. This idea is inspired by an exercise about the hidden parts of parenting from The Book You Wish Your Parents Had Read by Philippa Perry, though I'm pretty sure as a metaphor it can be quite widely applied.

Plan ahead illustration: A painter with passers-by contemplate the lack of planning ahead on a billboard that says Plan Ahead without the D fitting on.

Plan ahead

Plan ahead and avoid mistakes like this. Writing a card? Try air-writing first. 'Plan ahead' is also a nice example of a pleonasm. And I've lost count of how many times I've found this technique useful to draw a bike. This idea was shared with me from this Instagram account.

What is phubbing - snubbing someone or ignoring them for your phone - example: Someone sat in a cafe being phubbed by their friends on their phones while a parent and child walks by, gently heartbroken by being upstaged by a phone

Phubbing

Phubbing is snubbing people for your phone. We've probably all experienced it—heck, we've probably all done it at one point or another—or at least it's likely familiar. It could involve someone in a restaurant waiting for their friends to put their phones down, a family gathering where people are no longer talking to each other, a teacher without the attention of their students, or a child failing to get the attention of an adult who's trying to process some messages on their phone. Research on phubbing, mostly since the word was coined, says it largely has the effects you'd think it would. The effects vary with who's being phubbed and who's doing the phubbing: bosses and employees, family members, parents and kids, or partners. Whoever's phubbing who, snubbing is a suitable root word for it — it's not so nice to feel snubbed. I learned about phubbing from the Mind over Tech community, which also publishes a newsletter on forming better digital habits. The word phubbing has the unusual distinction of being created for an advertising campaign to sell a dictionary. See, for example, Knausenberger, J. et al. (2022). Feeling Ostracized by Others’ Smartphone Use: The Effect of Phubbing on Fundamental Needs, Mood, and Trust. Frontiers in Psychology, 13. https://doi.org/10.3389/fpsyg.2022.883901 Related Ideas to Phubbing Also see: For more phone annoyance, see Halfalogue.
