Why are trans-women more common than trans-men?

Short answer: It might be genetic. Human sexual behaviour, especially where stigma and taboos are involved, is notoriously difficult to study, so the real answer is that we just don't know. However, ...

Is there a theoretical maximum for IQ?

There are a few ways that you could answer this question. First, IQ is defined with a mean of 100 and a standard deviation of 15. But this is a normative score and relative to a given target ...

Do children inherit intelligence from their mothers and not their fathers?

The psychology-spot article mostly links to researches done on mice. Only three links are about human genetics. One is philosophical in nature, other two deal with mental retardation. This study says ...

Is intelligence (or mental ability) genetically transferred (inherited characteristic) from the parent to the offspring or is it an acquired trait?

You could start by reading "Intelligence: Knowns and Unknowns". This is a consensus article based on many of the world's leading researchers on intelligence. Empirical research suggests that ...

What are the reasons behind monogamy in humans?

First off, I think monogamy is a socially and culturally determined construct in man. In the animal world both monogamy and polygamy are encountered. Monogamy increases the chance of the survival of ...

Short answer: Yes. Modern estimates of global prevalence for autism are around 1-2% (for systematic reviews, see Baxter et al, 2015; Chiarotti & Venerosi, 2020). Prevalence rates appear stable ...

What does the statement mean "50% of happiness is determined by genetics"?

The statement 50% of happiness is determined by genetics is presumably talking about heritability estimates. It is probably talking about the percentage of variance explained by genetics. These ...

Is there anything called genetic anxiety?

Predisposition to anxiety can be inherited: Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external ...

Are schizophrenia and OCD genetically related?

Yes, there is almost certainly a genetic overlap between schizophrenia and OCD. Quantifying the overlap in variation requires genotyping a large number of individuals, and a lot of this cross-...

Best way to modeling ADHD?

The approach you would take will depend upon your level of analysis. For instance, one could choose to model an entire individual's behaviour (i.e. with heuristic models), the activity of neural ...

Do twin studies overestimate heritability?

It seems likely that some percentage of twin studies would fail to account for all the systematic environmental variables that connect their twins. In this case, the effects of these variables would ...

if IQ is inherited, is it from father or mother?

Both. The Independent article used a blog post as its main source. The blog post (which is no longer online) claimed to rely on a doc (scientific document) that actually hardly supports its main ...

Why is Autistic Spectrum Disorder compatible with the Schizophrenia Spectrum in the DSM-V?

We do not understand what causes either autism (ASD) or schizophrenia in the brain. There are some theories and ideas, but nothing conclusive and certainly nothing as simple as a single receptor. ...

Clues for genetic basis in Autism Spectrum Disorders

There is a clear heritable component that seems to be "highly genetically heterogeneous and may be caused by both inheritable and de novo gene variations" (Rylaarsdam, Gomboa, 2019). There has been ...

Excluding psychometry and interview methods, is there any physical or molecular method that can confirm mild autism?

No. The key term that will help you look for research about this is the word "biomarker". There are certainly correlations with autism and some of the measurement techniques, but they aren't ...

Are there any cases of a person with misophonia for which the condition has been passed on to their child?
