Optical Illusions And Delusions

Magicians skillfully exploit our perceptual expectations to entertain and amaze us, as do psychics—some of whom are charlatans, others are themselves true believers—victims of self-deception as much as they are responsible for deceiving others.

We, humans, are highly suggestible, which, for many, combines with an incomplete understanding of science and other complex subjects (and an overestimation of that understanding), leading to beliefs in paranormal phenomena, mystical experiences, and other weird beliefs (including conspiracies), confused as to what is real and what is not.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
