The Half-Life of Facts

Facts decay over time. And the time it takes to disprove or replace half of it can be predicted.

Data in medicine become half as relevant in 2-3 years. For exact sciences, 2-4 years.

Half life of facts and compound knowledge

If we want our knowledge to compound, we’ll need to focus on the invariant general principles.

Half-lives show us that if we spend time learning something that changes quickly, we might be wasting our time.

The Simple Math 

It takes about 6,400 hours of class time and studying to get a 4-year degree. Assume that it takes you only 5,000 hours to master your field.

While you are happy that you've prepared for your profession, the knowledge you've learned is fast becoming outdated. We can safely assume that in 10 years, 50% of the facts in the field would be outdated. This means that for you, just to keep up in your current field, you'd need to learn 5 hours per week, 50 weeks a year.

Trends To Consider

Meta-Learning

It's knowing how to learn. Learning itself is a skill, and knowing how to do it well is an incredibly valuable advantage.

Merely acquiring information is not learning....

Learning has 2 phases

Learning is a two-step process:

  • Read/listen: feeding ourselves new information.
  • Process and recall what you’ve just ‘learned’: connecting new materials to what we already knew.
Remembering the right things

You should not waste your time by committing unimportant details to memory. 

Your focus should be on understanding the bigger picture, on how things relate to each other.

We now face risks we can’t easily analyze

Our existence is invaded by science and technology as never before. For many of us, this brings comfort and rewards, but this existence is also more complicated and sometimes agitated.

Our lives are full of real and imaginary risks, and distinguishing between them isn’t easy. We have to be able to decide what to believe and how to act on that.

“Science is not a body of facts. Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not.”
