: OPTICAL ILLUSION
Then I did a little digging which I will share with you in a moment
: OPTICAL ILLUSIIN An optical illusion (also called a visual illusion is an illusion caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality.
Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where despite movement position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo, Poggendorff, and Müller-Lyer illusion. Physical illusions are caused by the physical environment, e.g. by the optical properties of water. Physiological illusions arise in the eye or the visual pathway, e.g. from the effects of excessive stimulation of a specific receptor type. Cognitive visual illusions are the result of unconscious inferences and are perhaps those most widely known.

PHYSICAL VISUAL ILLUSION
PHYSIOLOGICAL VISUAL ILLUSION
COGNITIVE ILLUSION
Physical visual illusions

A familiar phenomenon and example for a physical visual illusion is when mountains appear to be much nearer in clear weather with low humidity (Foehn) than they are. This is because haze is a cue for depth perceptionfor far-away objects (Aerial perspective).

The classical example of a physical illusion is when a stick that is half immerged in water appears bent. This phenomenon has already been discussed by Ptolemy (ca. 150) and was often a prototypical example for an illusion.
And the second is
Physiological visual illusions

Physiological illusions, such as the afterimages following bright lights, or adapting stimuli of excessively longer alternating patterns (contingent perceptual aftereffect), are presumed to be the effects on the eyes or brain of excessive stimulation or interaction with contextual or competing stimuli of a specific type—brightness, color, position, tile, size, movement, etc. The theory is that a stimulus follows its individual dedicated neural path in the early stages of visual processing, and that intense or repetitive activity in that or interaction with active adjoining channels cause a physiological imbalance that alters perception.
Cognitive illusions

Cognitive illusions are assumed to arise by interaction with assumptions about the world, leading to "unconscious inferences", an idea first suggested in the 19th century by the German physicist and physician Hermann Helmholtz. Cognitive illusions are commonly divided into ambiguous illusions, distorting illusions, paradox illusions, or fiction illusions.

Let break them down
Ambiguous illusions are pictures or objects that elicit a perceptual "switch" between the alternative interpretations. The Necker cube is a well-known example; another instance is the Rubin vase.

Distorting or geometrical-optical illusions are characterized by distortions of size, length, position or curvature. A striking example is the Café wall illusion. Other examples are the famous Müller-Lyer illusionand Ponzo illusion.

Paradox illusions are generated by objects that are paradoxical or impossible, such as the Penrose triangle or impossible staircaseseen, for example, in M. C. Escher's Ascending and Descending and Waterfall. The triangle is an illusion dependent on a cognitive misunderstanding that adjacent edges must join.

Fictions are when a figure is perceived even though it is not in the stimulus.
AFTER GOING THROUGH ALL OF THIS
Come to the surface a litle let's reason for a while
Remember the popular Phrase the more you look the less you see
: Can we relate with it
: Follow me very closely

Drawing a straight line between addiction to social media and political earthquakes like Brexit and the rise of Donald Trump, they contend that digital forces have completely upended the political system and, left unchecked, could even render democracy as we know it obsolete.

In 2007, Rosenstein was one of a small group of Facebook employees who decided to create a path of least resistance – a single click – to “send little bits of positivity” across the platform. Facebook’s “like” feature was, Rosenstein says, “wildly” successful: engagement soared as people enjoyed the short-term boost they got from giving or receiving social affirmation, while Facebook harvested valuable data about the preferences of users that could be sold to advertisers. The idea was soon copied by Twitter, with its heart-shaped “likes” (previously star-shaped “favourites”), Instagram, and countless other apps and websites.

It was Rosenstein’s colleague, Leah Pearlman, then a product manager at Facebook and on the team that created the Facebook “like”, who announced the feature in a 2009 blogpost. Now 35 and an illustrator, Pearlman confirmed via email that she, too, has grown disaffected with Facebook “likes” and other addictive feedback loops. She has installed a web browser plug-in to eradicate her Facebook news feed, and hired a social media manager to monitor her Facebook page so that she doesn’t have to.

“One reason I think it is particularly important for us to talk about this now is that we may be the last generation that can remember life before,” Rosenstein says. It may or may not be relevant that Rosenstein, Pearlman and most of the tech insiders questioning today’s attention economy are in their 30s, members of the last generation that can remember a world in which telephones were plugged into walls.

It is revealing that many of these younger technologists are weaning themselves off their own products, sending their children to elite Silicon Valley schools where iPhones, iPads and even laptops are banned. They appear to be abiding by a Biggie Smalls lyric from their own youth about the perils of dealing crack cocaine: never get high on your own supply.

One morning in April this year, designers, programmers and tech entrepreneurs from across the world gathered at a conference centre on the shore of the San Francisco Bay. They had each paid up to $1,700 to learn how to manipulate people into habitual use of their products, on a course curated by conference organiser Nir Eyal.

Eyal, 39, the author of Hooked: How to Build Habit-Forming Products, has spent several years consulting for the tech industry, teaching techniques he developed by closely studying how the Silicon Valley giants operate.

“The technologies we use have turned into compulsions, if not full-fledged addictions,” Eyal writes. “It’s the impulse to check a message notification. It’s the pull to visit YouTube, Facebook, or Twitter for just a few minutes, only to find yourself still tapping and scrolling an hour later.” None of this is an accident, he writes. It is all “just as their designers intended”

: IF YOU WHERE TOLD TO CHOOSE FROM 6 DIFFERENT BOX OF CHOCOLATE 6 DIFFERENT COLOURE Fine
HOW ABOUT YOU HAVE 21 DIFFERENT COLOURS WITH DIFFERENT FLAVOURS
🤓: Compare: WHICH WOULD BE MORE DIFFICULT TO MAKE A CHOICE
Let's discuss this for moment
Going forward
: IMAGINE A WORLD THAT IS VOID OF ILLUSION
: As against
A world where our choices are limited to just Good or Bad
Good better best
Bad worse worst
Slightly good
Not so bad
Pretty good
nicely bad
Very good
Evenly bad and the list is Endless
AVERAGE THESE DAYS IS A CRIME
Contempt is spelt as so much money in the bank
THE WORLD CAN BE A BETTER PLACE IF WE HAD MORE SATISFIERS THAN MAXIMISERS
: Satisfiers are those people who for things that satisfy them I mean just the things they need and they are : The always want to get the best of everything
Maximisers goes for perfection🤓: And if they don't attain perfection depression sets in: And every deal
We must must tell ourselves that every single minutes of our lives cannot always be awesome: IT IS OK TO JUST BE OK AT SOMETHING: No matter what the world throws at you you won't feel depressed cos you can't have it all
: AND CONTEMPT IS THE NEW WEALTHY
AND CONTEMPT IS THE NEW WEALTHY
OPTICAL ILLUSION AS A MAJOR TOOL USED TO GET AT YOU CONSCIOUSLY AND THROUGH YOUR SUBCONSCIOUS
: May be of know effect if only we learn contempt and agree that its is OK to be average and CONTEMPT IS THE NEW WEALTHY
