People often make incorrect choices when there are more than four variables.

Simple problems require reason, while the complex not so much. When there’s a large variety of items to choose from, get the one that maximises enjoyment.

People memorise patterns without even knowing.

The emotional brain, powered by dopamine, is paramount for good decisions.

People get addicted out of excitement, not necessity.

People get upset if what we expected didn’t come to fruition.

Being certain about something is a deceptive feeling.

Prize-linked savings accounts work because we like uncertainty.

Psychopaths don’t feel morality, and therefore, their wrongdoing.

People have a larger sense of loss than for win, even of the same value.

Never say that you wouldn’t do something in the way that that person handles it, because that person is who you would be at that moment in that situation.

When there’s a lot of information, we may infer the irrelevant. Cut down on the noise, focus on what’s important.

Don’t think too much.

A customer is worth a lifetime.

Lead people to the place they’re looking for, don‘t just give directions.

Reset customer expectations you can’t meet, even if they seem obvious.

Adjust your service to fit the customer best, but without intrusion into privacy.

Note at least five things unique about the customer, whether preferences or complaints.

When there’s a problem, apologise, review the complaint with the customer, fix and follow up, document the problem in detail to make sure it never happens again.

Make processes as efficient as possible.

Keep the hiring bar high: a bad employee may cause others to quit.

The speed of a group is the slowest one’s.

Make everything feel seamless: if there’s a problem you know you can solve, it should seem like it never happened.

Make the customer feel special.

I have a document open as I’m printing it. Then, I catch a typo. The part where it is hasn’t been printed yet. Why can’t I fix the typo and have the printer print out the correct version?

As Apple begins the dark mode revolution, it wants it to be everywhere. I love dark mode, and I agree. A couple of days ago they released a new version of the Safari Developer Preview with support of the CSS feature “prefers-color-scheme: dark”. There is only one website in the world that supports it, and I happen to really like it.

It’s really simple to take advantage of:

@media (prefers-color-scheme: light) {
//code that is//
}

@media (prefers-color-scheme: dark) {
//code that changes//
}

Yep, it’s my website.

For some weird reason the abbreviation for sine is sin and cos for cosine. This is madness compared to the beautiful and logical abbreviation for tangent and cotangent: tg and ctg respectively.

My proposal:

Quite obviously, I submitted them to my local ISO representative for review.
