Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Sir: We recently showed that birth complications combine with maternal rejection in predisposing people to violent crime ("Seeds of violence sown in the cradle", 3 September).

In commenting on our findings, Clare Prout (Letters, 11 September) felt that lack of financial resources, more than a genetic predisposition to be bad parents, was the crux of the problem, and that there was a simplistic suggestion that "the poor breed violent offspring".

First, we should clarify that while birth complications are a biological factor, they are more likely to be environmentally than genetically determined. Furthermore, the evidence for a genetic predisposition to violent crime is not strong.

Second, some of our most recent research has shown that poor people who are good parents and whose babies do not suffer birth complications actually have offspring with low rates of adult violence.

While we believe that poverty plays a role in predisposing to violence, it must not be forgotten that many poor people do not commit crime.

We are further convinced that biological factors also predispose to violence, and that to successfully prevent future violent crime we need to take into account the complex interaction between social and biological processes.
