The British PM has a history of racism and bigotry

Go on then! Explain how Eton promotes cultural Marxism

Where did I mention Eton?

You mentioned Boris Johnson's education.

the Mail Online reports

The low concordance rate of 33% in monozygotic twins demonstrates that illness vulnerability is not solely indicated by genetic factors

One final point: estimates that come out of this type of study are dependent on the environment the twins are living in. So results would likely differ if the same study were carried out in very different societies, or at different time points throughout history. Though this study benefits from using a large population-wide registry, study members were all Danish residents. The findings may not apply to different populations, with different ethnic and cultural makeups.

The study will add to the large body of literature exploring the role of hereditary and environmental risk factors for schizophrenia. However, it certainly doesn't mean we fully understand the causes of the condition, including the impact of environment on this condition

You mentioned Boris Johnson's education.

Boris didnt begin or end his education at Eton, any more than any of his friends ( and half of the British political establishment ) did.

I was thinking more of Oxford actually and his family background

Of course, there's always the possibility that Johnson has a mutant gene or two, too.

This from a twitter thread on eugenics. Not quite what we're discussing here, but related.

What about removing deleterious characteristics? This was a prominent aim of previous eugenic enterprises. Recent work has shown many cases of severe intellectual disability are due to what are called de novo genetic mutations.

I assume that these mutations don't only cause intellectual disability? Perhaps a it's a 'lying through my teeth' mutation..

Oh, the tweeter's credentials:

I work on human genetics and am honorary professor at the UCL Genetics Institute. I’m the editor-in chief of a journal which used to be called Annals of Eugenics. I just wanted to say that we now know from the latest research that eugenics simply would not work.

Bon point MD.

Well done! You have found a study with the lowest rates recorded. Good for you.

However, most studies demonstrate a concordance rate of between 35 % and 58% in Monozygtic twins. That doesnt sound high until you compare it to Dyzogotic twins of course, where the concordance is around 9% - 20% and the same applies to siblings. For those needing help the higher the concordance the more likely a strong genetic factor. Milder forms of schizophrenia tend toward lower concordance rates. That just suggests the increased importance of genes because when genes are loaded for more severe symptoms in a parent with schizophrenia ( or for example where both parents suffer from the condition rather than one) the incidence of concordance increases significantly.

Of course even MZ twins will experience environment differently and I never discounted the importance of that 20% nurture /environment factor did I? ( much as you would like to keep saying otherwise) 20% is a lot and can make a difference. I never said otherwise.

There is a whole raft of studies which would support the ablve. Moldin for example ( 1998) reviewd studies from the 1920's through to the 1980's and found an average concordance rate of 46% for schizophrenia amongst MZ twins even when children were raised in different environments /families. This compares to a rate of 14% in DZ twins.

OK, I don't believe earlier assertions that a person's personality is 80% down to genetics.

I didn't try particulatly hard to find a study of scizophrenia with a particularly low concordance rate for monozygotic twins. I just did a quick google.

Quite clearly, I am no scientist or geneticist. I am an interested person. I don't think we can assume BJ has some statesman like qualities in his genes. I find his father to be a snob and trading on his name and his wealth. I don't know anything about his mother. His brother and sister seem more genuine people.

His mother is an artist (apparently a good one), who has Parkinson's and is quite an active campaigner. She has made no secret of the fact that she has been hospitalised in the past with mental health illness.

Johnson has two brothers, but the second one keeps out of the spotlights.

aprilrose I honestly think I'd find it more satisfying discussing the price of baked beans with somebody.

Oxford doesn't promote cultural Marxism either. You really haven't a clue what you're talking about. In fact, cultural Marxism is a myth promoted by extreme right sites and accepted by the dimwits who follow such sites.

OK, I don't believe earlier assertions that a person's personality is 80% down to genetics.

Now we might be closer to a proper debate. Is personality a genetic predisposition or purely a result of environmental factors? Again we might go to the latest research which shows considerable evidence for the existence of some kind of genetic predisposition in perosnality disorders including those of psychopathy , although again, that environmental factor plays a part - for a pop psych point of view take a look at James Fallon on this. He is a proper academic but he also has an interesting take on psychopathy and its genetics.

But there are those who believe personality is a result of environment too. Mischels for example. You are entitled to your beliefs.

Oh dear. The conspiracy theorists are in force today.

Far from espousing Marxism members of the Bullingdon club sometimes dressed as Nazis. But of course BJ now thinks that was purely undergraduate pranks, the problem is the underlying philosophy still remains www.theguardian.com/politics/2019/jul/07/oxford-bullingdon-club-boris-johnson-sexism-violence-bullying-culture

During his time at Oxford, BJ was also a member of the Liberal Democrats not the Conservatives.

So two faced even then!

Incidently the Oxford Conservatives have severed ties with the Bullingdon even they know it is poison.

Johnson left Oxford in 1983. The Liberal Democrats didn't form until 1988/9.

I've got it! BJ was a cultural Marxist who dressed sometimes as a Nazi, a fore-runner of the Liberal Democrats and a Conservative. What more could you want in a PM?

Hahahahaha, spot on, Trisher! I bet he does a lovely Nazi salute too, while in costume.

GagaJo My grandson is part Mongolian and therefore will have the genes of Ghengis Kahn (most Mongolians do have his genes - reproduced prolifically). That is like saying my grandson has the genes to become a violent despot.
Your intellect and personality are inherited just as your physical attributes, but it's complicated. You get 50% of genes from each of your parents but children don't inherit the same genes which is why siblings are different. If two siblings had a DNA test the results may not be the same. Your character is developed from your upbringing but will be influenced by your personality and intellect. A child who has inherited a maths gene will have mathematical ability whatever his upbringing, although he might not make good use of it if his parents don't encourage him.

Might not encourage his dominance then. Wonder what he'd be like on horseback?

Oh april april april You are so naughty. I the full article on the NHS website re the Danish study into twins and schizophrenia. Things are not quite as clear cut as your summary suggests and there are several caveats and reservations re the generalisability of the study’s results. You seem to have a) not read to the end ( naughty) or b) you deliberately missed out the reservations ( also naughty).

I read the full etc

Whatever - I don't understand how anyone can trust him.
He's like feather in the wind - a white one.
And he's not in charge of this govt.
If only we had a stronger opposition. [sad}
