Cognitive bias occurs when we make subjective assumptions about people or situations based on our own perception of reality. This can lead to irrational decisions and judgement calls that affect those around us. They can alter the way you see everything without you even realising it.

Identifying the problem is the first step towards rational thinking. Here are 24 distinct biases that you need to be aware of - from "declinism" (believing the past was better than the present) to "fundamental attribution error" (judging others on their character but yourself on the situation).

Sometimes you get an overwhelming feeling that you just know something about a person or a situation; this is called intuition, and it’s often wrong.

I just migrated my photos off of Flickr. Yes, it's 2017, and I was still using Flickr. Why? Because I'd been using it since 2005, it's free, and the mobile app is… fine. But now that it seems like Flickr is joining the likes of AOL and Earthlink in the internet graveyard, it's clearly time to leave. Why did it take this long for me to leave to begin with?

Over the last couple of days, we've seen an interesting game played out at Google. An unnamed employee has said, in a 10-page memo that was widely circulated at the company, that the reason women are under-represented in IT is because they are psychologically different to men and, therefore, aren't as well suited to the jobs in the tech sector as men.

Now, that man has been fired according to reports today. I want to discuss a few things before coming back to the specific situation at Google.
