The trick is to validate your beliefs against competent people who have objectives orthogonal to your personal narrative.
For instance, don’t just read the sequences, read what the mainstream has to say as well.
And, while you should do this, it doesn’t lead to unitary truth without the further assumption that epistemology is universally agreed and fixed. The assumption is unrealistic, because epistemologies are often embedded in comprehensive belief systems. Imagine a group of Marxists and a group of Christians trying to settle their differences. Comparing different theories is necessary but insufficient to arrive at universal truth.
