The adoption of 'No Deal' is fascinating, isn't it?
At base, I think it's protection of self-esteem - at an extraordinarily fundamental level, where it is deeply bound to sense of self and how sense of self is constructed through perception and knowing.
It's so deep that it is repressed into the subconscious. Trying to reach it, engage with it, risks the unravelling of self - and can be perceived as threatening attack. It really is quite resistant to rational engagement.
Otto English has a fantastic Twitter thread where he asked people to contribute idea from psychology, sociology, neuroscience and philosophy to explain it. It's on his timeline.
For myself, I think about what I know from education, and my experience in education.
Educating children is not straightforward. It's about the transfer of information: most of it new and some of it complex . And that has to be done in a 'mass' situation (1:30 in state schools),
You are asking children to abandon what they 'know' for what they don't know (yet). This requires reorganisation of the knowledge that forms their basis of self.
Some of that information is new - and complex. Some of it is counter-intuitive: it goes against their 'daily experience'; the quotidian knowledge which serves them well for the functioning of everyday life.
Learning new things is uncomfortable: it requires effort, it takes up energy and processing time, it needs repetition and practice to embed - practice that needs to be artificially orchestrated.
Complex information needs to be broken down in order to be delivered - in manageable chunks, going from the known to the increasingly abstruse.
There needs to be a trust relationship to impart it. They need to believe the source of the teaching.
And there is a wide disparity in children in terms of how easily they learn. In a given class, about 5 will learn new and complex material quickly. The rest will require differing degrees of reinforcement, scaffolding, small-group repetiyiin: various strategies to enable learning are employed.
So , all very well in school - but what of when you leave school?
I suspect there are s lot of people who go through life feeling that much knowledge and information is 'elite': a conspiracy from which they are excluded (and why they might be excluded will be a reason they will fill in for themselves, based on whatever grounds their self-esteem can come up with - society favours women, people of colour, gay people ...).
I think they end up telling themselves that 'elite' knowledge is nothing more than an exclusionary game. It's a conspiracy.
I think they are uniquely predisposed to attraction to conspiracy theory knowledges. And information that is spread through non-mainstream channels. That reaches them through alternative networks, rather than 'elite' (mainstream) ones.
It reinforces their sense that mainstream knowledge is an elite network/conspiracy that they are excluded from. Here is knowledge that is similarly excluded! It is their knowledge.
It builds self-esteem. Finally, a knowledge tailored to their experience, a knowledge the elites can't see because their privilege excluded them from seeing it grow amongst the dispossessed!
Their relationship to knowledge is fragile - really - it's built on a very fragile relationship between self-esteem, self-identity and ways of knowing/things known.
If your sense of self is bound up with the idea that you have - uniquely - been initiated into s secret knowledge, that elevated you above those possessing elite knowledge - that, in fact, permitted you to see that elite knowledge was, in fact, just a lie, a ridiculous conspiracy, what do you do when that knowledge is a lie?
When 'Brexit means we will negotiate our position before leaving' turns into 'no Deal'?
I think what you do is you say: ' oh yes. I am super-clever. I saw that all along. I am not just one of the initiates into this Uber-elite cult, I am one of the inner sanctum. I saw the secret truth right from the start. I am, actually, one of the priests of this cult.'
Because the opposite - admitting you were wrong, even gulled - risks a catastrophe in the self-make-up that pulled you into the knowledge cult in the first place.
