Does anyone have any thoughts on heuristics versus strong induction?

A heuristic technique (/hjʊəˈrɪstɪk/; Ancient Greek: εὑρίσκω, "find" or "discover" ), often called simply a heuristic, is any approach to problem solving, learning, or discovery that employs a practical method not guaranteed to be optimal or perfect, but sufficient for the immediate goals.
Inductive reasoning (as opposed to deductive reasoning or abductive reasoning) is a method of reasoning in which the premises are viewed as supplying strong evidence for the truth of the conclusion. While the conclusion of a deductive argument is certain, the truth of the conclusion of an inductive argument may be probable, based upon the evidence given.

They seem very much the same although I suppose that heuristic suggests an invented technique and induction suggest a way of reasoning, which may be heuristic but perhaps need not.
I like to read about babies learning:
A Gopnik [onlinelibrary.wiley.com] suggests that a prelinguistic baby approaches the world inherently using a Bayesian methodology to understand its causality.

Good pun at the end. You are right, babies do think like this. I was reading a bit on the nervous system, and apparently nerve cells follow six orders of magnitude. It's fantastic how logic develops in the body.

For what it's worth, in 1974 at the Bronx High School of Science, after the intriductory computer course, my projects were all heuristics and machine learning. This was on an HP 3000 E, a refrigerator-sized machine with 16 K of RAM and which relied on paper tape for external storage. So my thought is that it has sentimental values for me. My big project was to have the computer cast and read I Ching hexagrams.

Fantastic!

Shortcuts / rules of thumb / heuristics are fine for inconsequential matters, such as, say, what color bedsheets to buy or boxers vs briefs or whatever. When it comes to one's beliefs about reality, then a little more rigor is in order.

I guess, but that is just lazy thinking and I will use an analogy to to explain why:

If I had zero gas in the tank, I'd just get more gas, I would not try to do anything until I was prepared.

Well, strong induction is preferrable if you have the overhead to burn, but I think the reason we have heuristics is for sheer efficiency (and evolution is a notoriously parsimonious 'designer'😉. This may be why AI ends up surpassing us, because if we can get over the energy and speed requirements, they can use strong induction every time instead of relying upon heuristics.

This is the exact reason why materials need to improve. We have tons of superconductors lying in the realm of possibilities, and we do nothing because we want to pay through the nose for energy.

Can you elaborate?

Yes, I can elaborate. A lot of people have that ability.

All jokes aside, a heuristic is an array that creates a dummy array that makes conclusions that do not actually follow in a logical way. For example, if you have the statement "There is a goat", and you think that the goat must have something else with it, based off of that statement, it's a heuristic. Strong induction is when there is no data loss in the array. So for example, if you take that same statement I just mentioned and think "Okay, so we have fur, hooves, etc." then that is a true statement. It is a good practical way to avoid the problem of affirming the subjective for every single time that such a problem is in the horizon.

I prefer to use deductive reasoning whenever possible. It's just more reliable.

Yeah, it is certainly an excellent poller!
