🧠Our brains construct a version of reality that is useful for survival.
🌈Our perceptions are a result of evolution and are not a direct reflection of objective reality.
👀Our senses can easily be deceived, leading us to perceive things that aren't there.
🐞Even animals can fall for optical illusions, highlighting the limitations of our senses.
🤔Our brains prioritize fitness over accuracy, leading us to see what is necessary for survival.
Why do our senses deceive us?
—Our senses deceive us because our brains prioritize fitness over accuracy. Evolution has shaped our perceptions to be useful for survival, rather than accurate depictions of the external world.
Can animals be deceived by optical illusions?
—Yes, animals can also be deceived by optical illusions. This shows that the limitations and biases of our senses extend beyond humans.
How does evolution shape our perceptions?
—Evolution shapes our perceptions by favoring traits that increase fitness and survival. Our brains construct a version of reality that is most useful for our survival, even if it doesn't accurately portray the objective world.
Do we all see the same reality?
—No, our perceptions can vary from person to person. However, there are shared experiences and commonalities in how our brains construct reality that allow for some level of agreement on what we perceive.
Is there an objective reality?
—The existence of an objective reality is a matter of philosophical debate. While our perceptions may not accurately represent the objective world, many scientists believe that there is an underlying reality independent of our perceptions.
