race and climate - a thought experiment

Black Africans will become an increasingly large share of the global population during this century, and many of them will settle abroad in countries that have winter.

How will that play out? African Americans adapted to cold climates, but they were forced to. 

There is an intriguing book about an African man from Togo who went to live in Greenland:

An African in Greenland - Wikipedia

***

The book recounts all the many episodes one expects from adventure literature: trouble at home, imagining a better life elsewhere, the struggle to find that life, disillusionment with certain hard facts that rub against bookish fancies, and the return, a state of mind where the author is more mature and more in touch with reality. Again, as Alvarez points out, the story reads like a fairy tale.

Readers discover the meaning of the Togolese bokonon, priest of the sacred python,

It amuses me that Bokonon is also the name of the founder of a satirical religion in Vonnegut's novel Cat's Cradle. 

Anyway, I have a hard time seeing large numbers of Africans settling other continents the way Europeans did, and for the same reason large numbers of Europeans are not settling the Sahara or Antarctica or Siberia. 

Arab and other refugees to Finland are unhappy with the climate:

Too smart to breed? - The Road to Idiocracy

It is well known that there is a negative correlation between IQ and fertility. This is the entire premise of the movie Idiocracy. Empirical evidence shows lower IQ people have more children and have them sooner while higher IQ people do the opposite. 

Countries in South America, the Middle East, and Africa are often cited as having low average IQs, and their populations are either stable or growing. In contrast, almost every high IQ country is experiencing population decline.

Attaining a middle-class standard of living in an industrialized country today requires either delaying or forgoing parenthood. The main reason, at least in the US, is that while salaries have increased even when adjusting for inflation, the cost of home ownership has more than quadrupled since 1950. 

No amount of tax cuts or other incentives will spur family formation in rich countries until more cheap housing is built.

But even accounting for the lower household income in 1950, the relative purchasing power was greater at the onset of the ’50s than it is today. For instance, it took about 2.5 years’ worth of paychecks for a person earning the average salary for white workers in 1950 to afford a new home, while the median cost of a new home today is nearly six times the average salary.

In contrast, housing is much cheaper in poorer countries, and so it is much easier to start a family. 

A system that discourages reproduction is a few generations from collapse. In this, perhaps the poorer countries of the world are being smarter in the long run. 

There are cultural factors as well which put North America, Europe, and East Asia at a disadvantage. Customs such as arranged marriages and bride price are frowned upon in more feminist societies, yet these same practices also ensure that the maximum number of young people find partners. 

Another more basic problem is that women generally will not marry or have children with men poorer than they are. In countries where women have mostly the same education and career opportunities as men, this means high-earning women price themselves out of the marriage market. If women spend their younger years getting and education and building a career, they end up as less attractive to high-earning men while at the same time being unattracted to low-earning men. 

Population decline in North America, Europe, and East Asia is inevitable until economic and cultural conditions change. 

on failure

Instead of saying "I failed", it's better to say, "I'm starting over". The only real failure is when you give up completely and don't try anything. Everything else is just a minor setback. I've had many such setbacks in my life. The life of the Japanese poet Kobayashi Issa inspires me.

He experienced many misfortunes in his life. His mother died when he was three, and three of his children died when they were young. His first wife also died a few years before him. In spite of that, he wrote numerous poems including thousands of haikus. His enormous body of work continues to be read to this day, both in the original Japanese and in translation. 

Failure is rarely fatal or permanent. The only sure things in life are death, taxes, and change. 

Some relevant quotes:

A minute’s success pays the failure of years. 

-Anonymous

Make new mistakes. Make glorious, amazing mistakes. Make mistakes nobody’s ever made before. 

-Robert Browning 

Mistakes are the portals of discovery. 

-Neil Gaiman

Failure is an attitude, not an outcome.

-James Joyce

what I wish was taught in schools about sex

I had "sex education" in 9th grade science class. It was mostly the biology of human reproduction, and nothing I didn't know already. What is far more important are the social and emotional aspects. 

Adults are reluctant to talk about sex in general and especially around children. Some oppose sex education because they think it will make teens more likely to experiment. I think the real reason is they feel embarrassed when they talk about it. 

Here's what schools should teach:

1. Fetuses have been observed masturbating in ultrasound images. Everyone experiences many orgasms long before they actually have intercourse.

2. The loss of your virginity will likely be a disappointing experience. 

3. Many people lie about their sex lives.

4. Stupid people boast of their sexual prowess to shame the intelligent and the gullible. 

5. About 20% of American men will have sex with prostitutes at some point in their lives. 

6. Smarter people have fewer children and have them later in life. They are also better parents.  

7. You'll lose money if you chase women, but you'll never lose women if you chase money. 

8. For every pot, there is a lid. 

9. Sometimes the juice is not worth the squeeze. 

10. Don't buy the cow if you get the milk for free. 

I think adults like having "secret" knowledge since they perceive that it gives them power over children. It's sort of like the Santa Claus mythos. 

If I had to put a number on it, I'd say sex with a woman gave me about $20 of happiness, and sex with a beautiful woman gave me about $40. $20 will get you a fast-food meal and a 6-pack of good beer with a few bucks left over. 

I'm short, shy, and have been fat most of my life. I'm probably in the 10th percentile for sexual attractiveness. Even so, I've dated many women and had a few girlfriends. My conclusion is that it's not that big a deal. 

an introvert "survival" guide

There is a military concept called the survivability onion. It has the following layers:

don't be in range of enemy weapons

if in range, know where they are to avoid detection

if detected, take cover to avoid being fired upon

if fired upon, have armor and a weapon for protection

I think something similar can help introverts in a world designed for extroverts. 

1. Realize that provocations, insults, etc. are inevitable no matter how much you avoid them. 

2. Avoid irritating people and circumstances

3. If there is an annoying stimulus, ignore it if possible

4. If the provocation continues, leave the vicinity if possible

5. If you must respond, use humor or sarcasm first

6. Be prepared to defend yourself physically before they touch you

Smaller people, especially men, are perceived as easier targets. The best self-defense weapon for most people is a quick-opening knife. They're cheap, portable, and very few people will press an attack against someone holding a knife.

If you're quiet and keep to yourself, realize that some people will provoke you because they want to "break you out of your shell". 

If you don't like to yell, swear, or use insults. a hard stare can deter aggression. 

It's best to conceal your intelligence. Showing it arouses resentment and makes others eager to humiliate you. 

If you look crazy or dangerous (unusual hair or clothes), people will leave you alone. There are pros and cons to this. 

Mere honesty is often perceived as the most insulting. 

If you're Christian, it's best to interpret "turn the other cheek" as "don't retaliate immediately". 

In any group of people. your basic options are conform, suffer, or leave. Be average if you want lots of friends.
