The Bigger Problem of Induction

Induction does not describe any actual process of reasoning.

The problem of induction shows that induction cannot be justified. The bigger problem is that there is nothing to justify. No one reasons inductively. The concept is a misdescription of other processes.

Properties

Induction (as traditionally described):

• is supposed to derive general conclusions from particular instances
• does not correspond to any actual reasoning process
• is a post-hoc narrative applied to conjecture and computation

Misdescription

Inductive reasoning reduces to one of two processes:

1. Conjecturing. They propose a general theory and notice it has not yet been refuted. This is abduction: conjecture followed by criticism. The generality comes from the conjecture, not from the observations.

2. Extrapolating. They fit a curve, extend a trend, or compute a probability. This is calculation. The output is a prediction, not an explanation.

Neither is induction. Conjecturing a theory is not deriving it from instances. Computing a prediction is not reasoning at all.

Dissolution

The problem of induction asks how induction can be justified. This question has no subject. There is no method to justify.

Induction is real in the way that Santa Claus is real: a real story, not a real thing. Presents appear under the tree. The explanation "Santa brought them" is wrong, even though the presents are real.

What people call induction is real. They arrive at theories, make successful predictions, navigate the world. But the account of how is wrong. They conjectured and tested. They computed and projected. They did not induce.

Example

"Housing prices have risen for a decade, so they will keep rising."

This describes the feeling of confidence in a trend, not a logical process. No one derives the prediction from the price history. They either have a theory about why prices will rise (conjecture) or they are extending the trend (extrapolation).

In 2008, the trend broke. The people who saw it coming were not better at induction. They had better theories.

The word "induction" is a label applied after the fact to processes that were never inductive.

Implications

1. The problem of induction is dissolved, not solved. There is no method of induction to justify.

2. Conjecture is the engine of reasoning. Creative conjecture, not passive generalization, is how knowledge grows.

3. Observation tests, not generates. Observations can refute conjectures but cannot produce them.

4. There is one form of inference. Deduction. Conjecture is creative, not logical. Computation is arithmetic, not reasoning.
