We see a minuscule fraction (0.0035%) of the electromagnetic spectrum, meaning our perception of physical reality is already an abstraction. When applied to complex human behaviors, objective "truth" becomes nearly impossible to discern, as it's filtered through cognitive shortcuts and biases.

According to evolutionary psychologists, our capacity for reason didn't develop to be a dispassionate tool for finding truth. Instead, it evolved as a social mechanism to justify our positions and persuade others. This explains why factual evidence often fails to change minds and can even reinforce existing beliefs.

Despite everyone seeing the same video footage of a controversial event, society fragments into rival interpretations based on hyper-partisan commentary. This demonstrates that access to the same raw data is no longer sufficient to create a consensus understanding of facts.

The reason smart AI experts continue to disagree on outcomes, despite new evidence, is that they operate from fundamentally different paradigms. One camp sees "always another bottleneck," while the other sees a pattern of overcoming past limitations. New data is simply used to reinforce these pre-existing worldviews.

We don't form beliefs based on neutral evidence. Instead, our existing identity acts as a filter that shapes how we interpret neutral events, creating new 'evidence' that reinforces our pre-existing beliefs, whether positive or negative.

People often agree on the facts of a political event but arrive at opposite conclusions because their internal 'threat monitors' are calibrated differently. One person's 'alarming authoritarian move' is another's 'necessary step for order,' leading to intractable debates.

When confronting seemingly false facts in a discussion, arguing with counter-facts is often futile. A better approach is to get curious about the background, context, and assumptions that underpin their belief, as most "facts" are more complex than they appear.

The human brain is not optimized for changing its mind based on new data, but for winning arguments. This evolutionary trait traps people in their existing frames of reference, preventing them from assessing reality objectively and finding effective solutions.

The human brain absorbs 11 million bits of information per second but consciously processes only 50. Our beliefs act as the critical filter, determining what we pay attention to and shaping our subjective experience, which explains why two people can perceive the same event completely differently.
