My brother and I may both be inductive reasoners. I now can't be 100% sure he's INTP anymore because there's something with his memory that's different from mine.
So he's rambling about something (his rambling consists of constant jokes) and it leads to tennis somehow. He gets the scoring of tennis wrong and almost makes me think I'm going crazy. At first, he says 10 (or 5, I can't remember because he brought up 5 at some point too), and I correct him that it's 15. Then he tries counting from there and thinks that the score ends in 45.
"No, it's 45. What is 15 + 15?"
"Maybe you're right..." I decided to look it up just in case because 45 simply didn't sound right to me. And guess what? It was 40. So I clearly yelled that in his face (of course, my household consists of yelling; I may be quiet in general but this is how we speak to each other lol).
I can't be 100% sure about his type, but I do know for certain that he used inductive thinking right here and thought not only that he was right but that he was going to be right. This doesn't rule him out as an INTP (our conversation after this makes me believe he's even less so), but he's definitely left with a lower percentage lol
Anyhoo, I'll explain the inductive reasoning part because I wrote this out in a couple of my drafts that I have decided to never post because I didn't want roaches on my blog (since they dealt with MBTI). Inductive users or inductive reasoners or inductive reasoning, whatever anybody wants to call it or the people using it, are pattern-seekers. They look for patterns that could likely be there. Inductive reasoning is the act of seeing random things and applying a rule to them to make sense of it and then predict the future with it.
Here're a couple of examples of inductive reasoning: trying to find the pattern of (2, 4, 6, 8...) and (13, 35, 64, 98...). The easier the pattern, the easier it is to discern the rule. The more certain you are the rule must be correct. Now, despite the fact that (2, 4, 6, 8...) are LITERALLY random numbers just like the numbers I chose in the second set are, someone using inductive reasoning will still assume there's somehow a pattern (especially in real life; with me, I just find it funny and call them coincidences). We all use this basic level of inductive reasoning. It's harder to find patterns in real life like this because the world is too "chaotic" in a way. So people who are more inductive are much more likely to force things in a certain order in order for the world to make sense.
My brother immediately assumed that a pattern had to play. He told me that the game of tennis should follow the rule of n + 15 (what I took from his 15 + 15; my brother isn't great at math so no one's gonna know his other "equation" lol), and he said it made no sense for the number to be 40. But he was clearly wrong even though my brother has a better memory than I do. He seems to sort things, in this particular instance, in his memory by patterns rather than their similarities (which is what I do; it bugs me when spoons are mixed with forks and vice versa). Now I can't be certain about this as this is one definite incident of induction that I found with him but the more he does this, the closer I'll get to him being an inductive user. I'm not sure, but I'll be using induction for this I presume. If not, this is deduction trying to rule out the conclusion that my brother may be inductive.
