How do I know what is true and what is just an opinion?

In today’s world of endless information, it’s easy to feel overwhelmed by conflicting claims. So, how do you separate fact from opinion? Understanding different types of reasoning, like inductive and abductive, can help.

Take the statement

“The Earth orbits the Sun.”

This is an objective claim backed by scientific evidence gathered through inductive reasoning—scientists observed patterns over time that led to this conclusion. Inductive reasoning builds general truths based on repeated observations.

But what if you don’t have repeated evidence? That’s when abductive reasoning comes into play. It involves making the best possible guess based on available information. For example, if you hear hoofbeats, you assume it’s a horse, not a zebra, because horses are more common. Abductive reasoning helps us make practical assumptions when we lack certainty.

To evaluate truth, ask yourself: Is this claim supported by solid evidence (inductive reasoning)? Or is it a logical guess based on what’s likely (abductive reasoning)? Understanding these can help you discern what’s fact and what’s opinion.

Here’s your premium extra.

Evidence. Inductive reasoning is evidence based; abductive reasoning is a best guess from limited evidence.
Subject: Reasoning.
Inductive reasoning finds patterns to predict future outcomes, while abductive reasoning makes the best guess based on available evidence. The Earth clearly revolves around the Sun, but hoofbeats outside might be horses or zebras. Abductive reasoning fills gaps by choosing the most likely explanation when certainty is unavailable. It’s useful—but it’s not proof. Opinions often lean on assumption without evidence. Good critical thinkers pause to ask whether a claim is truly supported by evidence.

In this project, claims are not merely asserted. They are attached to evidence, context, and traceable sources.
