Evidence of seasonal flows of small amounts of extremely briny water full of perchlorates on the surface of Mars.
They don't know if it's coming up from some kind of underground aquifer, seasonal subsurface ice melt, or the high salt content of the soil pulling out seasonal humidity from the air and producing transient moist soil layers that then leak out at suitable locations.
There are sometimes controversial discussions here, and I wonder how these conversations play out at meetups. Do you ever get an anarchist, a communist and a neoreactionary turning up to the same meeting? If so, does it cause problems? Or, indeed, do discussions about dust specks/torture or other controversial but apolitical topics ever get heated?
LW seems far more cool-headed than the rest of the world, and I am wondering to what extent it might be partially due to being online.
Personally, I have only gone to a few meetups, but I think I have managed to offend people :(
Do you ever get an anarchist, a communist and a neoreactionary turning up to the same meeting?
So an anarchist, a communist, and a neoreactionary walk into a LessWrong meetup...
I'm confused about where to post stuff when I post stuff to LW. I've xposted several articles (most recently this one) that seem like decent candidates for Main, but it seems that if I submit them to Main without them getting promoted, then they end up in the weird place that I'm guessing most people never check.
My current strategy is "post to Discussion so that people will actually see it, and hope that magically promotion happens".
..."magically" used deliberately to indicate that I don't know what the process for that is.
I found that variations on the following exchange are very common on programming forums:
Alice: Programming language feature X is misused more often than not. It's bad.
Bob: Every language feature can be misused. That does not make it bad.
Suppose Alice is correct on the statistics: most code that uses feature X uses it in a way that Alice and Bob would both agree to be wrong. Suppose Bob still disagrees with her over it making the feature bad. He disagrees not because he thinks the good uses outweigh the bad ones but because it is possible, in principle, to only use feature X the right way. Is there a specific name for their kind of disagreement?
Journaling, an extended argument for why you should do it.
Since January 2015, journaling has become the basis for everything I do, try and want. What I've found is that there's huge potential in a pen and some paper.
Keeping a structured notebook system is helping me monitor my habits, both good and bad. It makes it easier to keep tabs on my projects and to brainstorm solutions. Writing daily motivates me to try new things, and note what works and what doesn't.
Let's break down some of the reasons why I believe journaling is such a powerful tool for introspection, problem solving and goal setting.
In the short term, rehearse well with as close a simulation of your eventual stage as you can manage, or use prescription or nonprescription anxiolytics, or try one of the many speakers' tricks for reducing stage fright. Most of the latter probably won't work, but some might.
In the long run, the best way is probably exposure: doing a lot of public speaking, perhaps in front of progressively larger audiences.
It seems conventional wisdom that tests are generally gameable in the sense that an (most?) effective way to produce the best scores involves teaching password guessing rather than actually learning material deeply, i.e. such that the student can use it in novel and useful ways. Indeed, I think this is the case for many (most, even) tests, but also think it possible to write tests that are most easily passed by learning the material deeply. In particular, I don't see how to game questions like "state, prove, and provide an intuitive justification for ...
One easy way I can think of gaming such a test is to figure out ahead of time that those questions will be the ones on the test, then look up an answer for just that question, and parrot it on the actual test.
I know at my college, there were databases of just about every professor's exams for the past several years. Most of them re-used enough questions that you could get a pretty good idea of what was going to be on the exams, just by looking at past exams. A lot of people would spend a lot of time studying old exams to game this process instead of actually learning the material.
If you taught the principles of effective altruism to a rich person in (say) 1400, what would they have thought was the most effective thing to do with their money? What was in fact the most effective thing they could have done?
This video talks about high school curriculum design issues; advocating greater focus on concrete life skills and less of a focus on classes with "intangible" value like history or more advanced mathematics. If I recall correctly, he doesn't say anything about science class, which I think there's a lot to criticize there too. A lot of common counter-arguments to his point do not seem scientific. The argument that history teaches critical thinking for instance is very popular, but there's no good definition of critical thinking and research se...
I'm planning on running an experiement to test the effects of Modafinil on myself. My plan is to use a three armed study:
Each day I will randomly take one of the three options and perform some test. I was thinking of dual-n-back, but do people have any other suggestions?
This isn't worth a karma hit to me (though I'm risking one by posting this way), but I'm pretty sure that advanced atheist was making a joke. It wasn't an especially good joke, but all the comments seemed to assume aa was serious.
Who came up with Pascal's Mugging? Both EY and Nick Bostrom (pdf) present it as seemingly their own idea.
This is an open question about a brain-hack.
I don't believe the concept of love languages is big on LW, but searching the forum leads to a few mentions of them. It not exactly a data-driven concept, but anecdotally, spending time and acts of service are effective ways to make me feel loved, while gifts and compliments are not (they actually usually make me feel uncomfortable).
The primary concept of the love languages book is to change the way you show love from what you prefer to what your partner prefers (ie if your main language is touch and you a...
Does anyone have connection to whoever is answering this email address? hello@eaglobal.org trying to contact them.
For anybody more directly in the medical field:
Is there such a thing as a cryptic sinus infection / bronchitis / ear infection that produces fever and systemic effects but not local effects? I got a hell of a respiratory virus last weekend, the primary symptoms of coughing and nose issues are almost gone but my fever and general malaise are still around or even a little worse, and a doctor failed to see any indication of bacterial infection anywhere. I got antibiotics prescribed just in case and told to take them if I don't get better in the next few day...
Noticed a weird thing about myself today... Probably more useful for its vagueness, so reporting it here.
I owe a friend, who is also a colleague, 100 hrivnas. Recently, I found an unused gift certificate allowing to buy things for 150 hrn in a book shop, and thought, wow, I can just give it to her: her child has just started school, and the shop sells basic school supplies among other stuff - or better yet, since my child is going to school in a few years, I can just buy copybooks and give her two thirds of the loot. Great!
Then I went to the shop, and lear...
Are there any known deaths due to Quantum suicide experiments? Conversely, are there any known survivals in such experiments? (We should presumably not expect the latter for large odds of death, but just want the question to be complete.)
Is it okay to re-ask questions on open threads if they were not answered the last time the were ask on it? I had asked this question but received no answer, and I am concerened it would be spammy to re-ask.
I expect that most people are biased when it comes to judging how attractive they are. Asking people probably doesn't help too much, since people are likely to be nice, and close friends probably also have a biased view of ones attractiveness. So is there a good way to calibrate your perception of how good you look?
I'm really hesitant about posting about controversial topics like climate change because of the heavy mind-killing effect they have. But I was recently involved in a debate about climate change, and one of the opponents in the debate pointed to evidence supposedly supporting the 'global warming hiatus' in the past 15 years and that 90's climate models did not predict the hiatus. On the other hand, work by NASA/NOAA suggests that the supposed hiatus is actually illusory and an artifact of uncorrected ocean temperature data. Other sources suggest that the ti...
Just take a look [...] and check what your eyes tell you :-)
This is the same procedure that leads a lot of people to lose a lot of money trying to pick stocks, and a lot of other people to believe in the efficacy of prayer. Human eyes attached to human brains are very good at seeing patterns that aren't really there.
I am not a climate scientist and haven't looked at the data in detail. But, for what it's worth, when I eyeball the plots what I see is a highly noisy time series whose last 10 years or so do indeed look cooler than trend but not so much so that I'd want to rule out random variation as a sufficient explanation. And at least some people who have looked at the data in detail have arrived at the same conclusion; see e.g. passive_fist's second and third links.
I don't know whether those people are right, but what they say seems to me obviously credible enough that saying "just eyeball the data, it's obvious" is really bad advice.
[EDITED to add:] Maybe what's actually going here is different interpretations of "the hiatus exists". It seems fairly uncontroversial that (e.g.) the slope of the least-squares straight line fit to mean surface temperature fro...
This sounds very similar to journaling about ways my wife showed love each day
Journaling is focused on keeping track of what happened in the day, and what you perceived externally. That's not the point I had in mind with the exercise. The exercise was more to help your mind remember what it feels like to be loved. It's almost like training a muscle with weights or something. If you can bring up that feeling to mind more often, you might get used to it being there more often.
Journaling might help, but in a different way.
You could say that I'm feeling unhappy as a result of being lonely as a result of not perceiving enough love.
Thank you for this comment. I understand a little better.
I don't want/need stuff and a gift is more stuff wrapped in garbage which will eventually end up as garbage too.
If this has been your most common experience with receiving gifts, then no wonder you don't like it.
As someone who enjoys giving and receiving gifts, I would say that such gifts at least partly miss the point of giving gifts. It works much better when the gifts are thoughtful and something that the person receiving it actually likes.
There is weird cultural stuff around gift giving, different in different families and culture. In some cultures it is polite to pretend to like a gift you don't like. But in a romantic relationship, I think it is better to give feedback, and practice at getting better at it. Say it tactfully, but be honest. Then through several cycles of gift giving and feedback, adjustments can be made as you go along.
Perhaps you would prefer gifts more along the line of some sort of food that you enjoy that you could consume in a short period of time, or digital files that don't take up more physical space in your home. Those are examples I thought of that I think are less likely to fall into the category of "garbage wrapped in garbage". But you may have ideas that better suit you.
I know your topic is broader than just gifts, but I think in this example, you may not have had the experience of a gift done really well, with a lot of thought given to your preferences. When that happens, that feels pretty great, at least to me. But I also have had the experience of being given things that are of no use to me at all. If it's strangers I smile and nod, but for people close to me, I think it is worth bringing some assertiveness to the topic. In a long term relationship, I would not be satisfied with "That was kindly meant, but made my life slightly worse." Or maybe I would on occasion, but I would find it easier to accept if I had attempted to make the situation better in general.
In such a situation, I would communicate with my partner to see if we could find a way of doing things that was better for us both.
Maybe it should be "How can I feel positive emotions when people do nice things for me, irrespective of the format/modality of the nice thing, without having to consciously think about how it was a nice thing for someone to do."
Would it help to be able to separate in your head a bit the intent and the result? Because sometimes these do not match up.
You probably won't get to it being automatic to recognize and acknowledge someone's intent without spending some time doing it consciously.
If you observe people carefully over time, you may get a better idea of what their intent is. Or you could be more active and ask them directly (but politely) why they do the things they do.
Its seems I would like to make that lower-cost to me.
I think I'm missing something, because I'm not sure how that relates to what we are discussing. How would changing your perceptions of how love is shown make it easier to deal with when your wife takes some time to be with her friends?
It sound to me like your wife needs more time with her friends, but that the two of you also need more alone time together. Time is at a premium. I don't think it is reasonable to say "don't see your friends". But I do think there may be a way to achieve that, and achieve more time together. They don't have to be mutually exclusive.
I don't know your specific circumstances, so maybe your time really is that scarce. But from the outside, and from the limited information I have, I think "making time to be alone together more often without reducing time spent with friends" sounds like it might be important to the future of your relationship.
It seems like an incredible brain hack, that (assuming it works and is easy or not-terribly-difficult and has no side affects) would be wise for people in general to do. The end goal would be having all modes equal and highly sensitive.
I think that getting better at perceiving the other modes is achievable. I think that having more appreciation than currently you do for the other modes is achievable. I'm not sure that preferences for which modes you like best are so easily changed. I'm also not sure that having all modes equal and highly sensitive should be the end goal. I think that to you right now it looks like it would make your life easier, but it may not be optimal.
I also don't think that this is something that you necessarily have to do alone. If you can talk to your wife more, ask her what she's thinking, get her help in this project, that may help. When she's doing something that shows her love for you, she likely knows it, and could help you notice it, if you ask for help noticing.
I've had times in a relationship where I've asked my partner to help me when I'm clueless about something that they care about, and it has worked out well, though it can be uncomfortable at times. Sometimes expressing the confusion openly helps.
Thanks for your replies
If this has been your most common experience with receiving gifts, then no wonder you don't like it.
My issues with gifts are very layered and very deep, from going from middle class to "free-or-reduced-lunch" in middle school and becoming acutely aware of the value of things and what my mom was sacrificing for a new-but-cheap pair of jeans to a general avoidance of having stuff I don't want/use to a history of big gifts that were literally the opposite of "its the thought that counts". My wife and I don't rea...
