'Science' 2022 is analogous to the proverbial house (or grandiose mansion, in this case) built on foundations of quicksand. Consequently, it does not matter how intricate, elaborate, or carefully-crafted the building may be, when its foundations are non-existent.
In terms of science; this translates to meaning that when the foundational assumptions are false or absent; everything that derives from these foundations is wrong...
(Because there are a boundless number of ways of being wrong - but only one Truth; so if you are not even aiming for Truth, you will Not find it.)
This is how anybody can know that the climate or birdemic/ peck stuff is not just incompetent and fake science - it is not science At All.
The fact that the simplest and most basic foundations of these vast structures of words and numbers are non-existent, and the fact that there is not even an attempt to identify and remedy this situation - tells you literally everything you need to know.
What puts people off is the distraction of truly colossal quantities of 'research' that are completely irrelevant - firstly because nobody involved is even attempting to discover or speak the Truth; and secondly because the foundations are quicksand - so even-if the research was honest and competent (which it isn't), it is still literally meaning-less.
The proportion of such meaningless and dishonest research is 100% in many branches of science, and research more generally. And even in areas where some valid research is still conducted; it constitutes a such very small proportion that it becomes functionally-irrelevant.
This makes it - as one example - impossible honestly and competently to teach science at a high level; because the closer one gets to current research, the more must be discarded. It is regarded as intrinsically unacceptable to teach honestly, when that would entail ignoring/ excluding all (or almost all) published research on the topic for (say...) the past 40 years.
Yet the fact is that professional science has been destroyed by corruption to such as extent that the whole business is long-since unfit-for-purpose - when that purpose is genuinely Truthful understanding of real-reality.
And what is true for 'science' is also true for every other branch of systematic discourse. All are corrupted beyond usage - if one is judging usage in terms of the functionality that (50-100 years ago) would have been taken-for-granted.
(Of course, the real and aimed-at usage of 'science' 2022 and all other public and high-status discourses; is ideological and propagandistic.)
Law, economics, social sciences, the humanities are all broken, incoherent, functionally-useless - and the few remaining somewhat-functional discourses, such as some branches of engineering, are ever-more-rapidly being destroyed by subversion on multiple fronts...
And that destruction being covered up - or presented as progress - by bureaucracies and the media.
Therefore, this is Not a self-correcting cultural pendulum-swing. So long as the decline in cultural functionality is not just ignored and denied, but instead celebrated by the criteria of invert-valuation ideologies, so long will dysfunctionality accelerate towards irreversible global civilizational collapse...
A collapse which is actively desired by many including nearly all of those with power to cause it; and also many of those who are the intended victims.
In such a situation it is facile but ineffectual - and wasteful of our finite attention and effort - to critique what calls-itself science. It is All Wrong - since even when 'factually correct' - it will be interpreted and/or applied wrongly.
Best forget 'science'; and focus on more important - because eternal - things.
