What's the difference between a bellini and a blini? A bellini is a refreshing cocktail made with peach nectar and prosecco. A blini is typically a bite-size pancake often served with smoked salmon or caviar due to its Russian origins. Both are delicious in very different ways and yet sound almost exactly the same (like a homophone). The good news is that at a noisy party, even if you can't quite make out whether someone is offering you a bellini or a blini, the safe answer is always yes. In Russia, I am told, blini tend to be thinner, pan-sized pancakes rather than the topped, cocktail party style, thicker but mini pancakes they have evolved to in Western cooking.

So, the longer a period without incidents, a requirement to wear a hard hat may start to be taken less seriously and later ignored. The unacceptable becomes the norm, no longer seen as deviant. The term was used by Diane Vaughan when discussing the culture and events leading to the Challenger disaster. However, it’s easy to recognise it in much more mundane examples. Classic workplace examples where deviance may start to become normalised include: Wearing the correct protective equipment Sticking to speed limits Not sharing passwords Closing gates or tailgating Smoking Testing backups Handwashing and cleaning Thorough background checking Normalisation of deviance can be particularly tricky to avoid when failures are rare yet severe or with known but distant dangers, such as smoking.

The word amphitheatre derives from the Greek word amphi- loosely meaning on both sides or all around. For years, I've used amphitheatre for any large open galleried seating, but technically, as for the spectacular Minack theatre in Cornwall, England, if it's one-sided, then it's a theatre. You'll also see the same pattern in amphoras, which commonly have handles on both sides of the vessel, and amphibians who are at home on both land and water. Plus, related ambivalence, ambidextrous (amphi- Greek, ambi- Latin).

Helping with their solution may not help them solve their actual problem if it's not a good approach in the first place. An example from software development is a person asking how to extract the last three characters of a filename (solution X), because they want to know the file type (problem Y). After helping them do solution X, it still wouldn't solve problem Y as some files have extensions of more than three characters. Another example is a customer asking for help accessing their online account without realising that what they really want to do has to be done over the phone anyway. There's art and skill in respectfully answering questions and helping with what's asked while seeking to understand the real goal. And if you're asking questions, providing more context may help others provide better answers. In development, it saves time and effort. In customer support, it leads to happy customers. In design, it may be uncovering unmet needs. The name is indirectly from Eric Raymond in How to Ask Questions the Smart Way: "Q: How can I use X to do Y? A: If what you want is to do Y, you should ask that question without pre-supposing the use of a method that may not be appropriate. Questions of this form often indicate a person who is not merely ignorant about X, but confused about what problem Y they are solving and too fixated on the details of their particular situation."

Box breathing involves four steps repeated in sequence, each for an equal count: Breathe in Hold your breath Breathe out Hold your breath It's called box breathing or square breathing, as the four equal steps are like the sides of a virtual box. Counting to four is typical, though it can be more or less. Because of box breathing's simplicity and effectiveness, it's also used by the Navy SEALs—for example, ex-Navy SEAL Mark Divine can lead you through box breathing on video. I find meditation surprisingly difficult and the steps and simple counting of box breathing help me stay focused and free of distraction as well as any other technique. Even a few cycles of box breathing before a difficult conversation, a public talk, or after a challenging spell with our children helps me stay cool and be better.WWWBox breathing can help us focus on the present, reduce stress and anxiety by lowering cortisol levels, and generally relax and be calm.

The "flood" refers to the traditional release of books in the months leading up to Christmas. While there may be a book flood without gifting them on Christmas eve, it's such a nice extension that it seems worthy of its adapted meaning. Iceland has a long literary tradition, and a high percentage of Icelanders both read regularly and become authors themselves. Jólabókaflóð has its roots in various causes to do with wars, rationing, ancient sagas, and, I'd guess, also long winter nights.

For statements such as the results of a personality test, the effect is stronger if: we believe they are personalised to us they are sufficiently vague — handy phrases include "at times," "a tendency to," "some of," etc. they are mostly positive — we're more inclined to accept positive evaluations of ourselves than critical ones they come from a source of authority You may recognise these tricks from a horoscope or your star sign, magicians, fortune-tellers, fortune cookies, con artists and, perhaps, marketing. There's a fascinating magician's technique you may have seen called cold reading that uses the Barnum effect with other tricks ("I see someone with heart pain in your family.") to make it seem like they know a lot of personal details about someone at a first meeting. Originally from Bertram Forer, who called it "the fallacy of personal validation," it was later known as the Forer effect until Paul Meehl suggested it should be named the Barnum effect after P. T. Barnum (now of The Greatest Showman fame) for the way he could easily fool an audience with these techniques and to emphasize that we should all know and be on the lookout for being fooled. For that reason, I called it the same here. Bertram Forer ran an experiment with his students (pdf), giving everyone the same results for their individual personality assessment. Generally, the students all thought the same description applied very well to themselves. He used these statements taken "largely from a newsstand astrology book": You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. Your sexual adjustment has presented problems for you. Disciplined and self-controlled outside, you tend to be worrisome and insecure inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You pride yourself as an independent thinker and do not accept others' statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life. Not a bad description of me... I learned about it from a discussion of the Meyers-Briggs test (I'm an ENTP btw). Here's Paul Meehl advocating for the Barnum effect: "Many psychometric reports bear a disconcerting resemblance to what my colleague Donald G. Paterson calls “personality description after the manner of P. T. Barnum” ... I suggest—and I am quite serious—that we adopt the phrase Barnum effect to stigmatize those pseudo-successful clinical procedures in which personality descriptions from tests are made to fit the patient largely or wholly by virtue of their triviality; and in which any nontrivial, but perhaps erroneous, inferences are hidden in a context of assertions or denials which carry high confidence simply because of the population base rates, regardless of the test’s validity. I think this fallacy is at least as important and frequent as others for which we have familiar labels (halo effect, leniency error, contamination, etc.). One of the best ways to increase the general sensitivity to such fallacies is to give them a name. We ought to make our clinical students as acutely aware of the Barnum effect as they are of the dangers of countertransference or the standard error of r." Meehl, P. E. (1956).

Here's why: A common year has 365 days. 52 weeks is 364 days (52 x 7), so the year has 52 weeks plus one day as a bonus (364 + 1 = 365). So for most years, if your birthday was on a Friday, the following year it will walk forward to be on a Saturday 🎉 Leap years have another bonus day on 29 February. The bonus day means that your birthday will move forward two weekdays instead of one around leap years, however, how your birthday moves depends on whether it is before or after that date each year. Here's an example. Birthday after 29 Feb: Sun 9 Jul 2023 Tue 9 Jul 2024 (leap year) — leaps 2 weekdays on the leap year Wed 9 Jul 2025 Birthday before 29 Feb: Sun 1 Jan 2023 Mon 1 Jan 2024 (leap year) Wed 1 Jan 2025 — leaps 2 weekdays after the leap year Perhaps someone told me this when I was a child, and I was keeping close track of birthdays but even if they did it never sunk in. Hopefully, the little person leaping a day will help you, like me now, remember forever. It was pointed out to me that the changing weekday of your birthday is a very good thing—would seem a little unfair if you were stuck with a Tuesday all of your life.WWWYour birthday creeps one day of the week forward each year and two around leap years.
