This is 'Confirmation Bias - The Show' where Graham travels the full extent of the planet to find evidence to support the conclusion he has already drawn. He *constantly* employs buzz words such as "mainstream archaeology" to play on viewers' hesitance toward authority in the contemporary world and hypnotise them toward his framework. The truth is that there are a thousand conclusions which could be drawn by the many questions he raises in the show, but he steers the data in *every* case towards the one he had already drawn. The sad thing is that this quality discredits the interesting questions he raises and aligns him more with the conspiracy theorists of the flat earth hypothesis and astrology.
The show is engaging, entertaining and informative, but fails to meet several academic necessities, for example the total failure to present the rounded (and un-negatively-biased) picture of human history through the widely held academic narrative and *why* things have come to be understood in the way in which they have.
Science doesn't pretend to have all the answers, and rather takes the evidence it finds and compiles it into the wider established framework, which itself is built upon former material evidences. It is inevitable that this occasionally leads to erroneous conflations and miscorrelations and sometimes to research confirmation bias. On the whole, however, the scientific method has proved BY FAR the most effective at deriving fact.
Projecting scientists as if they are a cabal, desperately trying to conceal and discredit anything which challenges their narrative is extremely damaging, and completely opposite. On the whole, scientific scrutiny is absolute, and it is almost always scientists themselves whom rewrite a previously established fact, by using the scientific method.
Graham should stick to presenting these curios to his audience and maybe showing a few differing opinions on the reasons for them and letting the audience think and research for themselves, rather than shoe-horning and begging the audience to agree with him.
