The philosophy of disagreement
(Pictured: Is Bill Gates involved in a COVID-19 conspiracy?)
We want to tackle conspiracy theories. But first we visit must something we’re all used to: disagreement.
This isn’t about preferences: e.g. we’ll never agree on the best album of all time (you’re wrong). This is about uncoverable (at least in theory) facts. Does MMR vaccination lead to autism? Is human-induced climate change occurring? Are radio waves causally associated with cancer incidence? With access to the same information, intelligent, agreeable people disagree on what the facts of the matters are.
So who has the final say? Are some arguments ‘unsettleable’?
Experts
An issue: ‘experts’ get things wrong. Consider sports pundits, who are brought onto TV to discuss tactics. They may, for example, have experience of (A) playing the game or (B) of analysing it in detail as journalists. But they have shortfalls as fact-claimers: they may (A) lack critical capacity or (B) have never experienced playing the game at a high level.
Fans at home, then, can be more correct about tactics’ effectiveness: they have less access to resources and no relevant experience; and while their critical faculties are, on average, smaller, they are still right.
Epistemic peers
So let’s introduce ‘epistemic peers’: people who have access to the same arguments and evidence and who possess similar experience and intellect. This makes the debate more interesting since even epistemic peers disagree with each other!
Possible solutions:
Distribute degrees of confidence to arguments being true and find middle ground: e.g. P1 assigns 0.2 to ‘Bill Gates = a crook’; P2 assigns 0.8; therefore, assign 0.5. But why should one’s confidence have to be adjusted?!
Yet if we stand our ground, we’ll be disagreeing forever! Maybe agnosticism is the answer. Then what can we claim?!
Answer?
Perhaps only arguments and evidence themselves mater; and if people disagree in meta-disputes about them, such disagreements only form part of total assessments.
