Dr Brignell presents far better than I could the reasons for why we know they are lying. This is no vague conspiracy theory. Rather it is a detailed and well written summary of the main issues which ought to be well known to the public but for reasons he explains, generally are not.
It is to some extent forgivable when people adopt extreme positions out of misapprehension or delusion. It is quite another matter if they mislead others by deliberate falsehood. Politicians, of course, treat the lie as part of their professional equipment. Indeed, in some circumstances they are obliged to use it (when, for example, telling the truth about the economy would cause a run on the currency). In science, up to recent times, there is no circumstance in which a deliberate falsehood is justifiable. It requires at a minimum being drummed out of one’s learned society.
