It seems that you are not disagreeing with the concept of false consciousness. You just believe that a different group of people suffer from it. I hope you don't consider it too much of a caricature of your position for me to say that you think the elite labour under a lot of false beliefs but the working classes are able to see through all of this based on their own experience and clear insight.

I think at the core of this discussion, and false consciousness in general, is the question of how can we know what knowledge is true. I certainly agree with you, probably more than it appears in this thread, that we shouldn't take economics as some objective science. That's why I said up-thread that this is all discursive. But I think we are in real danger of throwing the baby out with the bath water and dismissing any economic knowledge at all. Larry Elliot has a good article here about economists' failings [1]. What I take from that is that, yes, forecasts are very shaky but economics itself analyses the failings and uses it to build better understanding (whether HMT uses that knowledge is a different question). SWL talks here [2] about the benefits of trade and compares dismissals of economic knowledge to climate denial. I think that's too strong but I am reluctant to dismiss the idea that we can gain empirical economic knowledge. (Incidentally if you know any good, pro-Brexit economics blogs please do let me know).

It seems that you implicitly rely on economics in some of your scenarios, thinking etc but then when you come against an economic idea or prediction you disagree with you just dismiss it with "oh well, economists are always wrong". I mean, if they are then how do you know the economics implied in your scenarios are correct? Why bother trying to get trade deals? Why bother making any economic arguments for Brexit if it's all unknowable? How do you know which of the US-style economic policies are the ones that created the growth? Surely there is some validity in testing hypotheses?

Continuing this skepticism, maybe you don't intend this but your comments read as if you think working-class people have some kind of natural, clear-headed insight from their lived experience that the elite and their academics don't have. I'm not sure from where you draw your certainty that you know what the entire working class is thinking, nor why a judgement based on individual lived experience should be any more reliable than one based on broader evidence. I don't think "economists missed the 2008 crash and got post-Brexit wrong so I can ignore them all now and go off what I see around me" is really a strong argument.

If all these expert economists with their models and their papers can't make a prediction why should you or I believe that you can? Maybe, like some economist, you've got a model that worked a few times but is going to come crashing down any day now. Shouldn't the same skepticism apply to you? Your whole scenario was based on the idea that the EU coveted the UK's growth rate but when I linked to World Bank data showing that in 2018 the UK underperformed literally every member state but Italy (ok, level with Germany) you still say that we're doing very well compared to other member states. See [3] for more recent data -- hardly comparing very well either. France is comparable and I wouldn't say the US is in a different ballpark. It doesn't seem like you update your priors in response to new data so what makes you think you are any more likely to be right? Or, to return to falsifiability, what would make you think you're wrong?

Coming back to false consciousness, I don't think it's the views themselves that are problematic but the way in which they are reached. I am doubtful that many people complaining about immigrants overcrowding their hospitals have looked at any evidence to decide whether the complaint is valid. I don't think "lived experience" is enough to make an objective, accurate assessment. You are right of course that we should critique arguments and not just take them at face value. For what it's worth, I'm a lukewarm remainer and I agree entirely with you about the Remain campaign's terrible campaigning. They also failed to mention the impact on N Ireland, which is far more significant and it's a terrible indictment of the British public that neither side bothered to think about the border. That didn't last long anyway...
