Not knowing when your next paycheck comes in literally hurts, researchers say

It perpetuates a vicious cycle of physical pain and psychological anguish.

Not knowing where your next paycheck may come from hurts, according to a 2016 study published in Psychological Science.

Researches looked at six studies, which found a strong link between financial insecurity and physical pain. It's not out of the question, past studies have shown psychological pain and physical pain share similar pathways in the brain. People suffering from depression and anxiety have more reports of feeling physical pain, including chronic joint pain, limb pain, back pain, and gastrointestinal problems — just symptoms of a larger problem.

"Overall, the findings show that it physically hurts to be economically insecure," the researchers concluded.

A separate study looked at the effect unemployment had on adults over time. The results weren't good. In the four-year study, published in the Journal of Applied Psychology in 2015, researchers found that unemployment caused people's personalities to shift. (Personalities were based on a test administered during the beginning and end of the study). Agreeableness declined, but with a distinct split between genders in how quickly and at what times their personalities' began to shift.

Author Christopher J. Boyce said that the results suggested unemployment has “wider psychological implications than previously thought."

The results of these studies have led researchers to argue that being in a state of poverty or financial instability psychologically compromises us. It's known in psychology as the “scarcity mentality" — the perception that separates the haves from the have-nots. When someone is in a constant state of worry about where their next meal is coming from, mental bandwidth becomes compromised, causing people to make unwise decisions.

“Our effects correspond to between 13 and 14 IQ points," Eldar Shafir, a psychologist at Princeton University and author of Scarcity: Why Having Too Little Means So Much, told Rutger Bregman in Utopia for Realists. “That's comparable to losing a night's sleep or the effects of alcoholism."

Shafir asks us to imagine the experience in a mental exercise: “If you want to understand the poor, imagine yourself with your mind elsewhere. Self-control feels like a challenge. You are distracted and easily perturbed. And this happens every day."

No one chooses to live a life of poverty. These studies show how easy it is to become stuck.

So, how do we help people escape?

"Poverty is fundamentally about a lack of cash. It's not about stupidity," economist Joseph Hanlon told Bregman. "You can't lift yourself up by your bootstraps if you have no boots."

Many believe a universal basic income might be the solution. The famous mincome experiment in Canada shows how people's lives improve dramatically when they have a little extra income to help them when times are tough.

Is this why time speeds up as we age?

We take fewer mental pictures per second.

  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.
  • The complexities of grownup neural pathways are no match for the direct routes of young brains.

Trauma in childhood leads to empathy in adulthood

It's not just a case of "what doesn't kill you makes you stronger."

Mind & Brain

  • A new study suggests children who endure trauma grow up to be adults with more empathy than others.
  • The effect is not universal, however. Only one kind of empathy was greatly effected.
  • The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
