DNA Proves Existence of a Designer

[Quick]

The point I am trying to make is that biases are so ingrained into us that they are impossible to escape from. There is no "overcoming" them. And we need bias because it helps direct our actions. Biases i.e. perceptions are actually the closest thing we actually have to rationality because without them, we are nothing but an entity without a brain. We developed biases as a species due to out large brains. Biases and perceptions give us a structure or paradigm or lens through which we view the world and we are better off with those paradigms than without them because we still do not have the brain capacity (processing power/good enough senses) to actually rationally think in a way that is at the root of how our brains actually work. Anytime you have something like death means that whatever entity that embodies that, it will have to adapt to that as the sole focus. We are necessarily geared towards preventing our own death. As such, we have adapted many mechanisms that do not "play nicely" with rationality. Fear is one such example of this. Someone who is terrified cannot think logically. A person full of fear thinks instinctively and this is much more at the core of our psyche than rationality ever will be. You might argue that a person is not always fearful. Fair enough, but consider that how interested we are in something is on a sliding scale and not an on off switch. This alone should tell you that we are far more variable and complex then can fit so easily into a rational system where logic is the primary mode of understanding.

Uh, straw man. I don't think he claimed that we were exclusively rational, only that biases could be counter-acted.

Introspection illusion
The introspection illusion is a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. In certain situations, this illusion leads people to make confident but false explanations of their own behavior (called "causal theories"[1]) or inaccurate predictions of their future mental states.

Correcting for the bias
A study that investigated the effect of educating people about unconscious biases on their subsequent self-ratings of susceptibility to bias showed that those who were educated did not exhibit the bias blind spot, in contrast with the control group. This finding provides hope that being informed about unconscious biases such as the introspection illusion may help people to avoid making biased judgments, or at least make them aware that they are biased. Findings from other studies on correction of the bias yielded mixed results. In a later review of the introspection illusion, Pronin suggests that the distinction is that studies that merely provide a warning of unconscious biases will not see a correction effect, whereas those that inform about the bias and emphasize its unconscious nature do yield corrections. Thus, knowledge that bias can operate during conscious awareness, is the defining factor in leading people to correct for it.

I don't see anything definitive here that says people can rid themselves of biases. What I see here is that the only thing that really happens is that their bias changes from one PoV to another. We are creatures with a limited grasp of reality. We can only take in so much information because we have not evolved to the point where we can take in all information from our surroundings. And ironically enough, the reason I know people have biases is because I have rid myself of a lot of them. This doesn't mean that I am not otherwise predisposed to bias, however, only that the biases I hold have changed. I might consider changing my mind if you could provide evidence for ridding oneself of bias via brain scan.
