> Meaning that the effect must be fairly strong to be observable in two studies with n=50? Do what now? Isn't the problem that it could have randomly happened (especially if people did a bunch of other similar studies that didn't observe an effect, and only these two were published)?

For a publishable effect at smaller n, the effect size needs to be fairly large. If you have a huge number of people in a trial, you can get statistical significance of negligible consequence. The problem with a single study of n=50 isn't the 50, it's that it's a single study.

That's not quite right. If the study is underpowered at n = 50 --- which is extremely likely --- statistically significant estimates are likely to be inflated. And as power declines, they also become more likely to have the wrong sign (e.g., the study will yield a positive estimate even though the true effect is negative).

I've noticed that retracing your steps (either literally if walking or not) helps enormously. For me it happens that I'm doing something on my phone, remember to do something else, switch apps to do it, and literally forget what it is. But by going back or checking the recent apps I find again the "trigger" of the original reminder. For example, you are checking [social network] and you see a post that reminds you to…

This works for me to an absurd degree. I sometimes remember, hours later, that I had some idea e.g. while showering or while brewing coffee. Returning to the bathroom or kitchen respectively helps me remember these ideas.

(It seems to me that the underlying claim of episodic memory might not be able to tell a difference.) There's a study listed on that page which observed that re-entering the same room did not improve recall.

Observation alone doesn’t necessarily give falsifiability. This requires an interaction of clear terminology with physics. In short, I was prodding at their definition of “doorways”.

Eh, that feels pedantic to me.

Communication involves active participation from the audience, in that a receptive and curious audience can be expected to make a good-faith effort to intuit what a communicator means when parts of the communication are left vague. This of course means that miscommunication is always possible, but the alternative is being paralyzed by overcommunicating details which are in most cases obvious.

If you are hypothesizing that some element of the doorway might change their results, that's a totally valid hypothesis, but you've not given enough information for me to intuit what elements of the doorway you think might change results, i.e. you're not doing a better job than the original authors of the study in communicating.

And notably, underspecifying what they mean by "doorway" doesn't invalidate the study, it just limits what conclusions can be drawn from their observations. I feel I have enough information about what they mean by doorway to draw useful conclusions from these studies. Of course it's possible I'm wrong (i.e. miscommunication has occurred), but you haven't communicated anything to me that would lead me to believe there's an important element of their definition of "doorway" that I'm missing.

This is why I advocate separation of work space and personal space, especially when working from home. It allows my mind to reset after physically leaving a space designated for work. If I don't, my mind will linger on work way more than I need to. At a minimum, I'd like to have separate PC for work, and even a separate desk for work. Ideally, I'd like a separate room for work but I don't have the luxury of having another empty room.

Have you ever walked into a room and found a vampire? No, not the sexy kind, but a foul creature with bony limbs and ashen skin? The kind that snarls as you enter, like a beast about to pounce? The kind that roots you to the spot with its sunken, hypnotic eyes, rendering you unable to flee as you watch the hideous thing uncoil from the shadows? Has your heart started racing though your legs refuse to? Have you felt t…

Can someone explain the meaning of this to me?

Is the encounter with the vampire similar to forgetting why one came into a room because when encountering a vampire in a newly entered room you forget everything before that and focus on the vampire?

The story is implying that whenever this happens to you -- forgetting why you came into a room -- the truth is that you were attacked by a vampire that made you forget the reason you were there, as well as the attack itself.

TOTP 2FA is terrible for this. I’ll sign into a website, pick my phone up to read the TOTP code, and instead end up on HN or Signal or something. Put the phone down after a couple of minutes, look back up to my computer screen with the 2FA prompt and go “oh yeah, that’s why I looked at my phone” That happens probably 50% of the time. And I wish that was an exaggeration.

Why don't more sites ask for the username/password and the TOTP code on the same form? Is there a downside to that approach? I've only seen it done that way rarely.

Probably because not all accounts have TOTP enabled, so it would be strange to ask for a TOTP if you don't have one.

Maybe with newer services that requires TOTP since day one is a possibility.
