[@Dinkydau00]

The thing about hiding things that could scare off people on dating sites is absolutely true. I have noticed that I contact people who have something "negative" that I don't care about. Also, I am a member of two different websites. On one, I made a very attractive profile and on the other one I didn't really care. The latter attitude gains me a lot of attention from people who contacted me mostly because of something controversial that they shared or wanted to talk about. Be completely honest about yourself and show the crazy things you believe will scare everyone away. It actually helps.

[@stevenelief6784]

My favourite scientist. Her TV stuff is brilliant, and understandable.

[@snois2]

[@edwardbates2562]

She is now my new hero. About to sit Maths exam and need her to be my coach!

[@codingkriggsofficial]

By the way, the graph she shows at 5:33 absolutely works for the popularity of things on the internet, such as youtube videos and news articles. If you say something controversial to get people in the comment section to bicker at each other, that will drive a lot of activity which will lead to recommendation engines pushing up its ranking. The end result: click bait, articles meant to irritate you, and popular authors being anything but qualified. The trollification of everything.

[@him050]

My hypothesis for this is that the people with the spread are people with things that some people love in someone, and others hate. So for a guy it would be him being absolutely ripped. Some women absolutely love that, and some women absolutely hate it.

[@Darth_Pro_x]

That's makes a really interesting question actually - Within a group of agents who are each searching for an optimal other agent within the same group, what's the optimal search strategy. is it still the 37% rule?

[@sorcererdm200]

@@Darth_Pro_x 37% rule works like this: With no other information, Given (N) number of options with a single unique(?) nonnegative parameter that is want to be maximized, Optimal search (or optimal stopping point, hence the name optimal stopping theory) is to 1) take (N*(1/e)) = N*(37%) of the options, ( where e = 2.7182 is eulers number) consider it as sample set and find the best option in them. 2) Then, you start looking at other options and stop when you find a better option than the one your sample set gave. 3) Fun trivia: This method gives you the best option of all the options with a probability of (1/e) = 37% For example, think you are choosing a random team in Fifa and you only care the star ratings they have, Now you can apply the "37% rule" to get the best team with 37% probability. But, your info is not limited with the star ratings only. You know that 5 star is the max. So, if you happen to get a 5 star team in any point of applying the rule, you can stop at that point, including "sample collection" In your question, If "being within the group" does not provide additional info, for ex, you know agent 007 is the best and you picked him similar to above case, then you can apply the "37% rule" to get the best agent with 37% probability.

[@comradepeter87]

I think it might be the case that couples with lower negativity threshold actually break up much before in the stage of their relationship, and those that have a high negativity threshold, take up longer for the build up and the final act. Hence, such couples don't exist in the dataset, and only those of the lower negativity threshold appear that are already successful.

[@Willard05]

That’s a really good point. I think what you are talking about is called ‘survivorship bias’.

When I read the title " mathematics of love" I said to myself that finally someone found what took me many years to find: the pattern of love, one that exist beyond the rigid statistics that never ever proved true simply because they missed the mathematics of awareness, knowledge and "need" of what we call Love! I was disappointed but maybe it's not yet time for humanity to open a new channel of understanding what they always assume beyond reach! Yet it was funny and the narrator had a positive energy.

[@atozedism]

Me too!

[@MCLooyverse]

I feel like looking for love is a really good place for a satisficer. It seems to me that, in the real world, you would have some sense of a lower bound for a good relationship, and an upper bound for a possible relationship before you start dating. Therefore you would not be limited to comparing each person with those who came before, but you could also reject all those under your lower bound, and stop when you are sufficiently close to the upper bound of what's possible. Throw in some extra rules to handle the possibility that you won't come across someone that close to the upper bound, and maybe throw in some rules for dating in parallel, and I think you have a much more accurate and optimistic model.

***** nuke the underdeveloped countries and your population growth would stop in a second. Then disallow couples with less then 110 iq to have more than one child, as a job with low intellect requirements would become a rare thing in the future. Having a huge part of the population being a burden for a society is not ideal, so in this scenario improving the average human DNA is imperative, as we need more and more ingenious people to keep growing, even as a species Therefore smart people HAVE to at least give birth to 2 children per couple, maybe more.

[@DeoMachina]

Pierfrancesco Greco I dunno man, I mean Japan got nuked twice and their population exploded. Check out Hans Rosling on this channel, he proves that you can actually stabalise population growth by reducing the number of deaths, not increasing them.

[@PigreKo]

DeoMachina I well know Rosling simulations, and I agree with him. In fact letting high mortality rate countries acquire better tech and welfare would grant them standards similar to ours, which in population terms means near zero growth and a stable society. Of course it way easier to kill them all!!! using just 1 or 2 nukes is not that relevant if you leave alive most of the population. Make a selection and actually nuke all the major cities of a country, spare relevant archaeological sites or cultural nodes, those you will nitpick with less destructive weapons. Invade the country and set aflame each village and city, decimate the remaining populace by a merit scale you pick. Aquire the land, let the remnant indigenous population work in your nation as second class citizens until they prove their fealty somehow and reach complete citizenship for them and their descendants. Enjoy a new found golden age. Repeat when needed.

The dealing with problems (lower threshold for negativity) and less divorce reminds me of risk management training I received.
