That video seems to be latching onto things in a very uninformed way. Of course the lockdown measures use behavioural science as a foundation, so does basically everything. They even said at the start when the public were crying out for harsher restrictions to be brought in that they were basing their timing of lockdown on behavioural science because the modelling shows people will only abide by strict lockdowns for so long.
Also seems totally irrelevant to complain there is no humanity or compassion in a scientific document. That isn't what the topic was about, have these people ever read a scientific paper before??
Edit - Just got to the end of the video. So the takeaway is Boris is lying to the public about a mild, winter virus, lying about deaths and using it to control people. Right... so what about Italy? The US? Spain?
Somehow the gov are simultaneously lying about a virus which is actually no big deal but also murdering the elderly? How can both those things be true at the same time?
