Why Can We Read Mammoth DNA but Not Dinosaur DNA?
A frozen mammoth tooth can hold readable DNA. A dinosaur fossil can preserve the shape of a bone for far longer. Here’s why those are different feats.
THE QUESTION LIBRARY HOW WE KNOW
Is luck real, or do we just see patterns in randomness?
Random outcomes can form real streaks. Learn how independent events, chance models, and face pareidolia help explain luck and perceived patterns.
THE SHORT ANSWER
Luck is a useful everyday name for favorable or unfavorable outcomes we did not control. It is not, by itself, evidence for a force that changes the odds. Random sequences can contain real streaks, and our perception can also add patterns that are not evidence of a cause. To distinguish these possibilities, define the outcome and test the pattern against an appropriate chance model.
- Random processes can contain actual streaks.
- Independence is an assumption that must fit the situation.
- A perceived face is not evidence of a hidden message.
WHAT WE DON’T KNOW YET
A particular streak may involve dependence, bias, skill, or changing conditions rather than independent chance. This evidence does not establish or exclude every metaphysical interpretation of luck.
WHAT WOULD CHANGE THIS ANSWER
A predefined, repeatable pattern predicting new results beyond an appropriate chance model.
