It’s difficult to know where to begin with this subject. There is so much I want to say, but nobody wants to read an essay.
Let me start by saying that the most fascinating* part to me of this whole story is in seeing the social reaction to the crime, rather than the crime itself. Humans, to me, are defined by two key attributes — we are irreducably social, and we are innately meaning-making. These attributes come together at a time like this, with a groundswell of social discourse that aims to make sense of what seems senseless. I see in this thread (and elsewhere) all the usual questions being discussed and argued about. Why did she do it? What were her reasons? What made her like this? What can we do about it? How do we feel about it? Could I have ended up like her?
People engage sociocultural tools to answer these questions. These include stories and mythology; the assumptions embedded in social norms, practices and rituals; commonalities in upbringing; and the subjectivity that derives from being subjected to particular developmental institutions. These create social representations of “rational” that suggest particular types of cause and effect. They suggest that somebody does something because they are trying to achieve something, and that something comes from a set of things that we understand. They suggest that people don’t act outside of the norms and assumptions that comprise what we view as “reality”
This is all very understandable. However, if you want to understand a situation like this, you have to engage in a process of stripping away such assumptions. Very, very few people go around killing babies. So if you want to understand somebody that kills babies, you can’t use the tools that work for 99.99% of the population. The edge case defies usual rationality. This makes something like A-level psychology particularly dangerous as the way to understand someone like Letby. When I did A-level physics, that gave me the tools to understand the physical world I can see around me. However, it would be dangerous to apply those to relativistic or quantum mechanics.
One of the assumptions you have to let go of is the idea that “reality” exists in the way that most of us experience it. Even at the most banal, we are used to the idea that there is an inside of our head where thoughts happen and an outside where actions occur, and the boundary between these is “me”. We don’t really reflect on the idea that thoughts are internalised models formed from all our past relationships and experiences (and even that is just my clumsy metaphor for what is really happening), meaning that the divide between self and other is fuzzy at best. We can see the effect on the schizophrenic when this divide is confused, however. The human being is a surfer attempting to balance a small rational surfboard on a boiling ocean of madness. And then we’re surprised when we see somebody whose surfboard has capsized.
And that’s before we start considering the delicate instrument that is the brain and the myriad ways that it can be physically damaged, with psychological consequences.
All this is to say that the more I study psychology, the less capable I feel to form quick conclusions about who, why and how Letby is what she is. I think you would need to spend a significant amount of time gaining her trust (and not in a manipulative way either — to gain trust, you have to be trustworthy). You would need to talk to her extensively about how she understands the world. You would have to understand the systems within which she has operated — her family system, her school system, her friendship systems, her workplace systems and so on. You would have to do a lot of work, and even then you might well not understand it because what counts as “rational” to her might not actually be explicable without being her.
Not that we should stop trying. But in the final analysis, I agree with those saying that the most useful thing we can do is address the risk systems that healthcare workers operate in, to try to make sure that edge cases like this can‘t do so much damage. We may not ever understand Letby, but we can think about our systems of controls, whistleblowing, monitoring and escalation. I couldn’t or wouldn’t want to stop the speculation — that’s what makes a society — but I also wouldn’t want us to take our eye off the ball of what is really important for our future safety.
*academically fascinating. I recognise that there is an unbearable tragedy at the heart of this, which is not fascinating at all. It’s just really sad.
