Effects of adoption on intelligence: 42% heredity, 8% environment?
I don’t do policy, but how about this one? In addition to all public policies aimed at getting rid of the achievement gaps between different groups, why not take an intensive approach? Continue with every program which is already under way, but add this one. Get every child who is under-performing to live permanently from...
Read MoreThe Rand Corporation had a look at the factors which led to effect war fighting, and found that ability was a key factor. Thanks to commentator Mac Tonight for the link. Determinants of Productivity for Military Personnel: A Review of Findings on the Contribution of Experience, Training, and Aptitude to Military Performance Jennifer Kavanagh Prepared...
Read MoreEstimates vary, and fall short of basic data quality. The highest estimate I can find for Afghanistan is IQ 83, and it is just that: an estimate. Say IQ 86 for Iran and Iraq, IQ 83 for Pakistan and IQ 86 for Turkey and we need not quibble about individual points, but the general range...
Read MoreDoes the world need another IQ test? There are many well-validated tests, and also a number of short tests suitable for large scale surveys, many of which take less than 10 minutes, and several useful ones which take less than 5 minutes. However, if you are searching for a good measure of the manifold panoply...

“Facing Reality” is Murray’s lament for America. He dissects the two key problems of race, and prescribes a reaffirmation of the American Creed of equality under the law, but is hoping against hope that those noble aims are achievable, and doubts his suggestions will be heeded. His short book might be briefly summarized as: “It’s...

Death and taxes may be inevitable, but it is only the latter which gather vocal apologists. Tax, these enthusiasts aver, is a good thing because it makes good things happen: hospitals, schools, roads, clean water and government inspectors maintaining standards. Certainly, taxes may provide services at better standards and lower costs than could be obtained...
Read MorePerformance anxiety is a hazard in all skilled behaviour. Whatever the level of motor skills, and however much repeated practice is put in, it is an essential part of human nature to worry about what may happen, and to contemplate the possibility of failure. This is not all bad, since anxiety can be the spur...

The UK Parliament Education committee has produced a report on left-behind white pupils from disadvantaged backgrounds entitled: The forgotten: how White working-class pupils have been let down, and how to change it (This provides the page from which you can download the report). It’s about time, you may say, that as everyone parades their genetics...

Many Western countries began immigration policies without feeling any need to monitor the long-term results. Indeed, many considered that immigration was an expedient response to labour shortages, and that the labourers, such as Turkish guest-workers in Germany, would probably eventually want to return home with their earnings at retirement. The United Kingdom seems to have...

The British Broadcasting Corporation is one of the world’s largest (35,000 employees including part-timers) and best funded news organisations, against which few can compete. Not only does it have a budget which in 2018-19 amounted to £4.0 billion ($5.6 billion), but it is virtually guaranteed the continuation of that level of income by a government...
Read MoreIf you select for some characteristic, and find that groups differ on other characteristics, it is natural to assume that the variable you selected might be causal. For example, if you select on the basis of genetics, and find differences, it would be understandable if you thought that genetics accounted for the other differences. Equally,...

One hypothesis about the Anglo-Saxon world is that Britain 1.0 has been superseded by Britain 2.0, such that the latter gets updated first, and the former always lags behind, under threat of being discontinued. As a consequence, the US fashions in race relations have late echoes in the UK. Here are two little stories about...

I recently commented on the UK report “Commission on Race and Ethnic Disparities”, which dared to suggest that systemic racism was not the major cause of race differences in Britain. The wave of criticism continues. One line of attack is that the Commission did not give sufficient weight to studies which show that racial minorities...

An official UK report “Commission on Race and Ethnic Disparities” has got into trouble by coming to the wrong conclusions. It has stated that the UK is not a racist state, and although there are instances of racism, in most ways the UK is a model of non-racism. The report says that the main source...

Max Roser does great work at “Our World in Data”, virtually all of which I read and retweet approvingly. He has just written a paper calculating the amount of economic growth which will be required to lift people out of poverty. Lots and lots of growth, he argues. I think it likely that lots of...
Read MoreI do not like the sound of “blood clots”. Many European leaders don’t like the sound of them either. Not nice, as my Granny used to say. It seems that some people who have received the AstraZeneca vaccination appear to have developed blood clots, 37 among 17 million people Europeans given the vaccine, so many...
Read MoreA Royal Family is a projective test: it is designed to be an emblem of a nation with which all citizens can identify. They need to see enough in that family to be able to imagine themselves being part of it. This family, by dint of some historical achievement, is chosen as the prime example...

On Monday England was given an indication as to how it will eventually get out of lockdown. Gradually, and in very careful stages, seems to be the answer. We are in our third lockdown, and have staggered through two false dawns. What is different now is that vaccinations have been completed on 17.7 million citizens...

At a time when there are concerns that Covid is being over-diagnosed, and its impact exaggerated, it is useful to look at another claim: that traumatic events in childhood have a major effect for the rest of a person’s life. On 18 November 1987 a fire at King’s Cross Underground station in London killed 31...

In this part of the world, the first side effect of vaccines has been political. Europe’s nations are now competing to get vaccinated, and the ructions have been considerable. From the start, the UK took a vaccine friendly stance. Early on it decided that vaccination was the long-term solution, and all else was merely a...
Read MoreA General Practitioner is the English term for what in other countries is called a Family Doctor. She rang us up last week to offer us vaccinations, asking three questions: are you fit and well; have you had a flu vaccination in the last week; have you had allergic reactions to anything? Then we were...

In the continuing story of coronavirus, this week brings two stories about limitations. The first is that production of both Pfizer and AstraZeneca vaccines in Europe is faltering, and from Monday supplies will be reduced for the next few weeks. There have been production problems, of the sort which happen in all manufacturing. It should...
Read MoreI had always imagined that death had a certainty to it. Taxes are a close second, but death is easier to diagnose. The problem comes when the cause must be written on the certificate. A heavy drinker who falls downstairs has an accidental death, but it was brought on by his habitual drinking. Someone who...
Read MoreScience and politics make awkward bedfellows. Science is more concerned with the truth, or ought to be; politics more concerned with expediency, survival and the avoidance of blame. For that reason, politics is closer to human nature. It is natural to simply hope for the best, to take precautions a little too late, and relax...
Read MoreYou know the story, but here we go again. The standard account of sex differences in intelligence is that there aren’t any. Or not significant ones, or perhaps some slight ones, but they counter-balance each other. The standard account usually goes on to concede that males are more variable than females, that is to say,...
