Neil deGrasse Tyson: Scientists’ brains are wired to see differently

Scientists are expert observers. Because of this, they can help us develop a keener view of the world — the cosmos.

  • There are many people who have discomfort engaging with a scientific perspective of the world — for some, for instance, it conflicts with what they were taught during their religious upbringings.

Surprising Science
  • What climate scientists have called a Hothouse Earth emergency, has been called "optimal" by a leading economist.
  • That optimal scenario is based on "the most unrealistic and dangerous assumption in the history of economics."
  • Leading scientists warn strongly against the methods that economists use. "No amount of economic cost–benefit analysis is going to help us. We need to change our approach."
