Do you have proof? Most knowledge came out of discoveries with the scientific method, which is not perfect but rigorous enough to avoid those human errors.
What you are describing is inherently human, biases affect both the educated and uneducated, but only one group was trained in critical thinking - at least that was the purpose of education (less and less today)
My only evidence is the number of people on HN who seem to believe in unsubstantiated conspiracy theories and falsehoods, and obvious partisan propaganda. The premise that HN is hard to fool is undone by simply spending enough time here.
The point is, using HN comments as a quality or truth filter doesn't work, especially since most people here only ever engage with the comments. It's the blind leading the blind here.
