12 Mind-Bending Perceptual Illusions
By Steve Stewart-Williams

Everyone loves a good optical illusion. Most people first come across them as kids, and are instantly transfixed. And most of us never quite outgrow them. Even cats seem to enjoy the occasional optical illusion!

The good news, then, for humans and nonhumans alike, is that our illusions seem to be getting better over time. In the age of social media, lots of people are making and sharing them, and the best ones are quickly going viral and setting the new standard. In effect, our illusions are evolving culturally to be more and more powerful.

But although perceptual illusions are fun, they also have important philosophical implications. They show us in a clear and unambiguous way that we don’t directly perceive the world around us. Perceptual experience is a simulation—a mental model—that doesn’t always correspond to the reality it aims to depict.

As mob lynchings fueled by WhatsApp messages sweep India, authorities struggle to combat fake news
By Annie Gowen

More than a dozen people have been killed across India since May in violence fueled primarily by fake social media messages, as officials struggle to rein in this growing technology-driven menace.

The perpetrators are largely villagers, some of whom may be using smartphones for the first time. Inflamed by fake warnings of child-trafficking rings or organ harvesters sent via the WhatsApp messaging service, they have resorted to vigilante justice — attacking and beating to death people who often were innocent.

…

To control the subsequent violence, state authorities hired “rumor busters,” including Sukanta Chakraborty, 33, a musician who was paid about $8 a day to travel from village to village in a van equipped with a loudspeaker, warning of the dangers of fake news. He and two others were beset by a mob wielding bricks and bamboo sticks in a crowded market Thursday.

“They killed him. He was pleading to the mob that he was only doing his duty,” Tanushri Barua, Chakraborty’s wife, said in a telephone interview. “No one listened to him.”

Preface to Dangerous Ideas
By Steven Pinker

Many of our moral and political policies are designed to pre-empt what we know to be the worst features of human nature. The checks and balances in a democracy, for instance, were invented in explicit recognition of the fact that human leaders will always be tempted to arrogate power to themselves. Likewise, our sensitivity to racism comes from an awareness that groups of humans, left to their own devices, are apt to discriminate and oppress other groups, often in ugly ways. History also tells us that a desire to enforce dogma and suppress heretics is a recurring human weakness, one that has led to recurring waves of gruesome oppression and violence. A recognition that there is a bit of Torquemada in everyone should make us wary of any attempt to enforce a consensus or demonize those who challenge it.

“Sunlight is the best disinfectant,” according to Justice Louis Brandeis’s famous case for freedom of thought and expression. If an idea really is false, only by examining it openly can we determine that it is false. At that point we will be in a better position to convince others that it is false than if we had let it fester in private, since our very avoidance of the issue serves as a tacit acknowledgment that it may be true. And if an idea is true, we had better accommodate our moral sensibilities to it, since no good can come from sanctifying a delusion. This might even be easier than the ideaphobes fear. The moral order did not collapse when the earth was shown not to be at the center of the solar system, and so it will survive other revisions of our understanding of how the world works.

Psychology Desperately Needs a Massive Influx of Skepticism
By Lee Jussim Ph.D.

Skepticism is crucial for good science in a way that has some similarities to why removing weeds is crucial for a healthy garden. Bad weeds can choke off healthy plants; bad science can choke off good science if, like a runaway weed, sometimes, bad science becomes popular, highly funded, and adopted as a basis for law, social policy, and personal use. It then takes away attention and resources from good science and leads to impressive promises of personal and social change that end up as dead ends, or worse.

Even plants that have some value like scientific claims that have some truth but are wildly oversold can mostly function as weeds, if they go too far. Consider ivy that covers windows and doors; bamboo that takes over a yard; and scientific claims that have some truth but are wildly oversold.

Science has a long history of bad weeds, everything from bad astronomy theories choking off good ones to bad medicine. Social psychology has a disturbingly impressive track record of such “weeds,” including social priming, the power of the situation, stereotype threat, implicit bias, ego depletion, power posing, stereotype inaccuracy, stereotype bias, grit, delay of gratification, the Stanford Prison Experiment, facial feedback, and more (and more and more).

The Dangers Of Online Conmunity
By Ben Sixsmith

The internet benefits a lot of people who have sought like-minded acquaintances, friends, and even lovers — yet it is a dangerous place. All across social media are what I call “conmunities”: not quite cults, lacking their organization and militancy, yet still drawing fragile, desperate people into exploitative relationships based on false hope, narcissism, and greed. Features often include:

1. Charismatic leaders who act as mentors on the basis of selective information, rather than the more rounded perspective one might gain from acquaintance in real life.
2. Clear hierarchies of status and influence, based more on popularity than expertise, experience, or achievements.
3. Underacknowledged financial interests.
4. Claims to exclusive truth.
5. Severe resistance to criticism.
6. “Us against the world” dynamics.
7. Reinforcement of destructive behavior.
8. Relationships based more on shared beliefs and preferences than shared experiences.

These features make conmunities vulnerable to herdlike conformity, financial or narcissistic exploitation, and latent social ties based on shared opinions, taste, and language that are hard to transform into trust, cooperation, and emotional fulfillment.
