    We can’t prove that the world we live in wasn’t created last Thursday, with our memories, the growth rings in trees, and so on created by a (near) omnipotent trickster to deceive us. But science and rationality give us tools for determining what’s worth taking seriously, and sorting out the reasonable, but unconfirmed, claims from the unverifiable hogwash.

    And even then it’s probably not a hard rule as much as a good heuristic: the older a source is, the more careful you should be citing it as an example of current understanding, especially in a discipline with a lot of ongoing research.

    If somebody did good analysis, but had incomplete data years ago, you can extend it with better data today. Maybe the ways some people in a discipline in the past can shed light on current debates. There are definitely potential reasons to cite older materials that generalize well to many subjects.





  • Knowledge is what happens when you’ve evaluated enough evidence to reject the null hypothesis that something is false. If you haven’t seen the evidence, but still think it’s true or false (you don’t lack belief), then you have a belief about it. As such, knowledge is a type of belief with extra justification.

    If I’ve reviewed enough evidence I’m comfortable saying I can reject the null hypothesis, that is I have a belief that it’s knowledge, I’ll call it as such. If I haven’t, I’ll couch my confidence in my belief accordingly.





  • In my mind, the issue is that cars are incentivizing drivers to use high attention controls like touchscreens while driving. Actions that need to happen while driving, whether they’re directly vehicle operation, or something like air conditioning or media volume, should be simple low-attention controls, ideally with tactile feedback. Keep it simple for your brain, keep focus on the road.

    I have volume buttons, skip, jump backwards, and a numpad on my dash that interact with phone apps via Bluetooth. Maybe there’s a physical (or voice) control that can be added to the dash or wheel to interact with map/navigation apps. Using the touchscreen is dangerous, and a car shouldn’t provide a reason to do so. I’d rather solve the problem another way.

    But if a touchscreen is required to update the clock, or do Bluetooth pairing, that’s fine. There’s no reason to need to do those while driving.


  • I have a small (4-5") screen that has my clock, media information, which displays my backup camera feed if I’m in reverse, which I think is a modest improvement over the all-analog option, and a huge step up from the deathtrap touchscreen configuration. In my mind, the touchscreen is the point where it starts to drop off quickly, as it stands I don’t think I’d buy a car with a touchscreen that doesn’t lock it out while moving.


  • Smart switches are programmable, and can easily configure smart switches and lights. You can get a touch screen interface to home assistant, and do all of that on it, embed it on the wall. It doesn’t need to be an app on your phone.

    Voice is definitely easier and more convenient, with HA being more configurable and difficult.

    There are always going to be trade-offs in life, but you’re definitely getting convenience in exchange for privacy here

    Yeah don’t listen to Dave Ramsey. I remember hearing him speak on TV as a kid and something just felt off about him, but not quite as bad as Suze Orman.

    I don’t think he’s a scammer, and some of the stuff he says is perfectly sensible and useful, but he (a boomer) also gives advice that isn’t how he got rich, to millennials and co, who will never ever get rich following it. Structurally that makes him pretty out of touch, and suggests anyone who listens to him should do so critically.

    That’s putting aside that he’s also kind of just telling people to do capitalism harder, and everything that comes with that.
