Education

Teaching at Oxford began as early as 1096 AD, making it one of the oldest universities in the world. The Aztec Empire was only founded in 1428 AD — more than 300 years after Oxford started.

For the first time in history, women now outnumber men among university graduates in most developed countries and globally. In the United States, women earn about 57% of all bachelor's degrees. In the OECD, 56% of new graduates are women. This trend is driven by higher female educational attainment rates and greater ambition in academic achievement. However, gender gaps remain in STEM fields — particularly engineering, computing, and physics.

Despite significant global progress in education, women still constitute about two-thirds (63%) of the world's 773 million illiterate adults. This gender gap is most pronounced in sub-Saharan Africa and South and West Asia. Illiteracy among women is directly linked to higher rates of child mortality, poverty, and early marriage. UNESCO estimates that each additional year of education for girls increases their future earnings by up to 10% and reduces infant mortality.

Malala Yousafzai, born in Pakistan's Swat Valley, began advocating for girls' education under the Taliban's oppressive ban from age 11, writing an anonymous BBC Urdu blog. In 2012, at 15, she survived a Taliban assassination attempt — a gunman shot her in the head on her school bus. She recovered, moved to the UK, and in 2014 became the youngest person ever to win the Nobel Peace Prize, sharing it with Kailash Satyarthi. She founded the Malala Fund, advocating for 130 million girls out of school globally.

Multiple controlled studies show that regularly writing down three things you are grateful for — for as little as three weeks — significantly increases life satisfaction, reduces depressive symptoms, and improves sleep quality. Gratitude activates the brain's reward circuits and increases dopamine and serotonin production. A landmark 2005 study by Martin Seligman found that a 'gratitude visit' — writing and personally delivering a thank-you letter — produced the largest increase in happiness of any positive psychology intervention tested.

Psychologist John Bowlby and researcher Mary Ainsworth established attachment theory: the emotional bond formed with caregivers in infancy creates an 'internal working model' that influences all future relationships. They identified four attachment styles — secure, anxious, avoidant, and disorganized. Research shows that a person's attachment style in childhood predicts relationship patterns in adulthood, conflict resolution style, and even parenting behavior with their own children.

Psychologist Daniel Kahneman discovered that people don't evaluate experiences by their overall average — they remember them based on the peak (most intense moment) and the end. In a famous study, patients undergoing colonoscopies reported less total pain when doctors deliberately prolonged the procedure slightly at the end, at reduced discomfort. The longer but less painful ending dominated their memory. This is why vacations with a great last day, and presentations that end strongly, are remembered more positively.

Priming occurs when exposure to one stimulus influences responses to a later stimulus — often without any conscious awareness. In one famous experiment, people who unscrambled sentences containing words about old age (bingo, wrinkle, Florida) subsequently walked more slowly out of the lab than those who hadn't. In another, people exposed to money-related images became more self-reliant and less helpful to others. These effects reveal how deeply unconscious associations guide everyday behavior.

Psychologist Mihaly Csikszentmihalyi identified 'flow' — a state of optimal experience where a person is fully immersed in a challenging activity, losing track of time and self-consciousness. Flow occurs when task difficulty closely matches the person's skill level: too easy causes boredom, too hard causes anxiety. Athletes, musicians, surgeons, and programmers describe flow as one of the most satisfying states a human can experience. Research links frequent flow states to higher life satisfaction and wellbeing.

Memory is not like a video recording. Every time you recall a memory, your brain reconstructs it from fragments, often filling in gaps with plausible-but-false details. This is why eyewitness testimony is notoriously unreliable, and why leading questions can literally implant false memories. Psychologist Elizabeth Loftus demonstrated that people can be made to remember entire events — like being lost in a shopping mall as a child — that never happened.
