Evolutionary Biology, Perception, and Quantum Reality

The Case Against Reality is an interview with neuroscientist, quantum physicist and professor at University of California, Irvine, Donald D. Hoffman regarding a study he published here. His argument is essentially that human beings did not evolve to perceive the world accurately, but rather, advantageously. He claims that what is advantageous to perceive may look nothing like "reality," provided an external reality exists at all. He goes so far as to posit an idealist metaphysic grounded in his studies in quantum cognitive science, claiming that a very possible structure of the world could be a network of first-person perspectives creating a pseudo-collective reality which we all experience together. What type of epistemic state would the explanations posited by Hoffman leave us in? On one hand, "truth" goes out the window, but on the other, we have immediate access to all the "objects" of our perceptions and, to some extent, create those "objects" ourselves.

  1. This is awesome! By the way, this reasoning is quite similar to the rationale given by both Descartes and Locke that the chief function of the senses is to be a practical guide to aid us in survival.

Negative Afterimage

Reber Shukri Professor Vaughn Negative afterimage is a stimulus which elicits a positive image. In order to experience this, one can look at a bright source of light and then look away to a dark area. The way negative afterimage works is when the eye's photo-receptors which are the rods and cones adapt to over stimulation and lose sensitivity. The photo-receptors which are constantly exposed to the same stimulus will fatigue their supply of photo pigment, resulting a decrease in signal to the brain. The way negative afterimage connects to perception is because of bottom up processing where the stimulus influences what we perceive. https://www.youtube.com/watch?v=szy8iNCljlQ <Link to the video

Illusions that Confuse Multiple Senses

In this video, several illusions are shown that deceive your senses. Illusions such as the Zöllner Illusion and the Poggendorff illusion confuse our bottom up processing by tricking our vision. However, our vision isn't the only sense that these illusions can confuse, blind individuals presented with raised versions of the same illusions are also confused by them. These illusions effect the visual and touch systems by confusing our bottom up processing by tricking out sight and touch. https://www.youtube.com/watch?v=Je1mkzRU5rc&t=64s

How Your Expectations Mess With The View of The Present

In this video the waiters and waitresses give the customers a water menu with fancy different names. They then taste the differently packaged water. Since they were convinced that they were actually different types of water, they were comparing them and actually tasted a difference. The reasoning behind this is, since they were told that they were different, they believed what they were told. They perceived what they expected it to be. This is is an example of how your expectations mess with your view of the present. Therefore, they tasted the water to be different but in reality it was tap water the whole time in different bottles.
