I worked at a place once where the process was "Quit thinking, and have a meeting where everyone speculates about what it might be." "Everyone" included all the nontechnical staff to whom the computer might as well be magic, and all the engineers who were sitting there guessing and as a consequence not at a keyboard looking.
I read this book and took this advice to heart. I don't have a brass bar in the office, but when I'm about to push a button that could cause destructive changes, especially in prod, my hands reflexively fly up into the air while I double-check everything.
A weird, yet effective recommendation from someone at my last job: If it's a destructive or dangerous action in prod, touch both your elbows first. This forces ou to take the hands away from the keyboard, stop any possible auto-pilot and look what you're doing.
Related: write down what you're seeing (or rather, what you _think_ you're seeing), and so with pen and paper, not the keyboard. You can type way faster than you can write, and the slowness of writing makes you think harder about what you think you know. Often you do the know the answer, you just have to tease it out. Or there are gaps in your knowledge that you hadn't clocked. After all, an assumption is something you don't realise you've made.
This also works well in conjunction with debug tooling -- the tooling gives you the raw information, writing down that information helps join the dots.
Yes! I do this when doing anything destructive ("rm -rf dir", "drop db", etc.) - i just stop and say out loud what environment I'm in, what the command I'm running is going to do and why I am doing it. This is in a remote-work situation, in an office I would have someone come double check the really destructive things before hitting enter..
Don't confuse them with facts: everyone knows that "socialist" means "left-ish thing I don't like". And in Starmer's case, the key word is "left-ish". Maybe "left-ish-ish-ish".
I don't miss working there.
