It’s *what* you need. 🧭 👋 I’m Kasley Killam, author of *The Art and Science of Connection* and an expert in **social health** — the often-overlooked third pillar of wellness, alongside physi...

But are test scores really telling us the full story? Our current education system defines intelligence as a student’s ability to recall and reproduce information on a standardized test. This narrow approach may reveal how well a child performs *under specific conditions*, but it says little about their **true potential**. 📚 The real issue? Thi...

Sabine Hossenfelder investigates life's big questions through the lens of physics, particularly Einstein's theory of special relativity. She highlights the relativity of simultaneity, which states that the notion of "now" is subjective and dependent on the observer. This leads to the block universe concept, where past, present, and future all exist simultaneously, making the past just as real as the present. Hossenfelder also emphasizes that the fundamental laws of nature preserve information ra...

Harvard physician Aditi Nerukar explains how to rewire your brain’s stress response to live a more resilient life. **💥 You're not weak. You're human.** Stress isn’t a flaw to fix — it’s a biological force we all live with, just like gravity. But modern life turns it chronic, silent, and often shameful.

Psychopathy is actually a spectrum, and care is the variable that differentiates true psychopaths from highly empathetic people. Here’s why that matters, and how it can be treated, according to Professor Abigail Marsh. Humans are among the most altruistic species that we’ve studied, due to our alloparental instincts – a trait we evolved into that allows us to care for offspring who are not our own. Across species, the ones who alloparent the most appear to be the most altruistic. Very altruistic...

Sure, IQ is important, but is it as impactful as emotional intelligence? Renowned psychologist and author Daniel Goleman explains. The concept of emotional intelligence (EQ) can be traced back to ancient philosophies, but it was Goleman’s bestseller ‘Emotional Intelligence’ that popularized the term in 1995. According to Goleman, while IQ and smarts can get you good grades and jumpstart your career, it's EQ (what the psychologist often refers to as EI) that sets apart the top performers and lead...

Can we let go of the need to win arguments without losing a part of who we are?
