About - Project Euler
I've written my program but should it take days to get to the answer?
Absolutely not! Each problem has been designed according to a "one-minute rule", which means that although it may take several hours to design a successful algorithm with more difficult problems, an efficient implementation will allow a solution to be obtained on a modestly powered computer in less than one minute.

Basic Error Rates
This page describes human error rates in a variety of contexts.

Most of the error rates are for mechanical errors. A good general figure for mechanical error rates appears to be about 0.5%.

Of course the denominator differs across studies. However only fairly simple actions are used in the denominator.

The Klemmer and Snyder study shows that much lower error rates are possible--in this case for people whose job consisted almost entirely of data entry.

The error rate for more complex logic errors is about 5%, based primarily on data on other pages, especially the program development page.

WHO | Priority environment and health risks
also: http://www.who.int/heli/risks/vectors/vector/en/

Environmental factors are a root cause of a significant disease burden, particularly in developing countries. An estimated 25% of death and disease globally, and nearly 35% in regions such as sub-Saharan Africa, is linked to environmental hazards. Some key areas of risk include the following:

- Unsafe water, poor sanitation and hygiene kill an estimated 1.7 million people annually, particularly as a result of diarrhoeal disease.
- Indoor smoke from solid fuels kills an estimated 1.6 million people annually due to respiratory diseases.
- Malaria kills over 1.2 million people annually, mostly African children under the age of five. Poorly designed irrigation and water systems, inadequate housing, poor waste disposal and water storage, deforestation and loss of biodiversity, all may be contributing factors to the most common vector-borne diseases including malaria, dengue and leishmaniasis.
- Urban air pollution generated by vehicles, industries and energy production kills approximately 800 000 people annually.
- Unintentional acute poisonings kill 355 000 people globally each year. In developing countries, where two-thirds of these deaths occur, such poisonings are associated strongly with excessive exposure to, and inappropriate use of, toxic chemicals and pesticides present in occupational and/or domestic environments.
- Climate change impacts including more extreme weather events, changed patterns of disease and effects on agricultural production, are estimated to cause over 150 000 deaths annually.

ed.:
Note the high point at human origin (Africa, Middle East) and Asia. Low points in New World and Europe/Russia. Probably key factor in explaining human psychological variation (Haidt axes, individualism-collectivism, kinship structure, etc.). E.g., compare Islam/Judaism (circumcision, food preparation/hygiene rules) and Christianity (orthodoxy more than orthopraxy, no arbitrary practices for group-marking).

I wonder if the dietary and hygiene laws of Christianity get up-regulated in higher parasite load places (the US South, Middle Eastern Christianity, etc.)?

Also the reason for this variation probably basically boils down how long local microbes have had time to adapt to the human immune system.

Tropical disease: https://en.wikipedia.org/wiki/Tropical_disease
Tropical diseases are diseases that are prevalent in or unique to tropical and subtropical regions.[1] The diseases are less prevalent in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation. However, many were present in northern Europe and northern America in the 17th and 18th centuries before modern understanding of disease causation. The initial impetus for tropical medicine was to protect the health of colonialists, notably in India under the British Raj.[2] Insects such as mosquitoes and flies are by far the most common disease carrier, or vector. These insects may carry a parasite, bacterium or virus that is infectious to humans and animals. Most often disease is transmitted by an insect "bite", which causes transmission of the infectious agent through subcutaneous blood exchange. Vaccines are not available for most of the diseases listed here, and many do not have cures.

Does left-handedness occur more in certain ethnic groups than others?
Yes. There are some aboriginal tribes in Australia who have about 70% of their population being left-handed. It’s also more than 50% for some South American tribes.

The reason is the same in both cases: a recent past of extreme aggression with other tribes. Left-handedness is caused by recessive genes, but being left-handed is a boost when in hand-to-hand combat with a right-handed guy (who usually has trained extensively with other right-handed guys, as this disposition is genetically dominant so right-handed are majority in most human populations, so lacks experience with a left-handed). Should a particular tribe enter too much war time periods, it’s proportion of left-handeds will naturally rise. As their enemy tribe’s proportion of left-handed people is rising as well, there’s a point at which the natural advantage they get in fighting disipates and can only climb higher should they continuously find new groups to fight with, who are also majority right-handed.

...

So the natural question is: given their advantages in 1-on-1 combat, why doesn’t the percentage grow all the way up to 50% or slightly higher? Because there are COSTS associated with being left-handed, as apparently our neural network is pre-wired towards right-handedness - showing as a reduced life expectancy for lefties. So a mathematical model was proposed to explain their distribution among different societies

THE FIGHTING HYPOTHESIS: STABILITY OF POLYMORPHISM IN HUMAN HANDEDNESS

http://gepv.univ-lille1.fr/downl...

Further, it appears the average left-handedness for humans (~10%) hasn’t changed in thousands of years (judging by the paintings of hands on caves)

Frequency-dependent maintenance of left handedness in humans.

Handedness frequency over more than 10,000 years

Psychopathy by U.S. State by Ryan Murphy :: SSRN
Rentfrow et al. (2013) constructs a cross-section of the “Big Five” personality traits and demonstrates their relationship with outcomes variables for the continental United States and the District of Columbia. Hyatt et al. (Forthcoming) creates a means of describing psychopathy in terms of the Big Five personality traits. When these two findings are combined, a state-level estimate of psychopathy is produced. Among the typical predictions made regarding psychopathy, the variable with the closest univariate relationship with this new statistical aggregate is the percentage of the population in the state living in an urban area. There is not a clear univariate relationship with homicide rates.

Washington, D.C., harbors the greatest share of psychopaths in the US, "a fact that can be readily explained either by its very high population density or by the type of person who may be drawn a literal seat of power."

Chengyu - Wikipedia
Chengyu (simplified Chinese: 成语; traditional Chinese: 成語, pinyin: chéngyǔ, lit. "set phrases") are a type of traditional Chinese idiomatic expression, most of which consist of four characters. Chengyu were widely used in Classical Chinese and are still common in vernacular Chinese writing and in the spoken language today. According to the most stringent definition, there are about 5,000 chengyu in the Chinese language, though some dictionaries list over 20,000.

They are often referred to as Chinese idioms or four-character idioms; however, they are not the only idioms in Chinese.

Land, history or modernization? Explaining ethnic fractionalization: Ethnic and Racial Studies: Vol 38, No 2
Ethnic fractionalization (EF) is frequently used as an explanatory tool in models of economic development, civil war and public goods provision. However, if EF is endogenous to political and economic change, its utility for further research diminishes. This turns out not to be the case. This paper provides the first comprehensive model of EF as a dependent variable.

Race, Religion, and Immigration in… | Democracy Fund Voter Study Group
Figure 2 The Relationship between 2011 Attitudes and Vote Choices in 2012

Third, although perceptions of the economy are related to vote choice in both years—unsurprisingly, people who believed the economy was doing worse were more likely to vote for the out-party Republicans—its effect is similar in both years. This suggests that the 2016 vote choice was not uniquely about “economic anxiety.”

The results also show that certain factors were less strongly related to voters’ choice in 2016 than they were in 2012: social issue attitudes, economic issue attitudes, and, more notably, party identification. The smaller impact of party identification reflects the larger number of defections in 2016, as compared to 2012.

What stands out most, however, is the attitudes that became more strongly related to the vote in 2016: attitudes about immigration, feelings toward black people, and feelings toward Muslims. This pattern fits the prevailing discourse of the two campaigns and the increased attention to issues involving ethnic, racial, and religious minorities in 2016.(v)
