In Tromsø, Norway, the sun does not set for two months. The assumption is that it destroys sleep and mental health. The Tromsø Study found sleep barely changes across the seasons. And the further north you live, the more positive your attitude toward the extreme light cycles. The locals have simply organised their culture around it.
Unsolicited advice does not just fail to persuade. Research shows it produces a behavioral backlash that makes people more committed to what they were already going to do.

On August 21 1986, a lake in Cameroon exploded without fire, lava, or sound. A cloud of carbon dioxide flowed down into the valleys and killed 1,746 people and 3,500 animals before sunrise. In the nearest village, six people survived out of 800. It can happen again.
Einstein did not fail mathematics. His 1896 Swiss certificate shows perfect scores. His Nobel Prize was not for relativity. He played no role in building the atomic bomb and described signing the Roosevelt letter as the greatest mistake of his life. Three myths. Three corrections.
On a hot July afternoon in Paris, the Eiffel Tower is approximately 15 centimetres taller than it was in January. It is also leaning. Both are measurable, both are documented, and neither is a metaphor. Marco Bellinari explains the physics and the history behind the most famous iron structure in the world.
People who talk less are perceived as more intelligent. The research behind this is uncomfortable because it is not a compliment to quiet people. It is a cognitive bias that operates on everyone regardless of what they know about the person they are judging. Here is the mechanism.
Genghis Khan killed 40 to 60 million people. He also created the first direct trade route between Europe and China, a system of religious tolerance that exempted all faiths from taxation, and the largest contiguous legal system in history. Both things are true.
There is an animal the size of a fingernail that does not die of old age. When injured or starving, it reverses its life cycle to its earliest juvenile form and starts again. Scientists have documented it completing this process over ten times in succession. Its name is Turritopsis dohrnii.
