When we draw general conclusions from specific observations or examples, inductive reasoning refers to the use of these particular facts. If we observe that bread comes out of a toaster every single time it is toasted, then we can inductively conclude that bread all placed in the toaster are toasted.
Contrary to what you might think, deductive reasoning involves applying a principle or rule to specific situations to arrive at a conclusion. If we are able to see fur on an animal, and know it’s a mammal, then we can conclude that they are mammals.
There have been instances in my life where people made broad and sweeping statements about groups of people without any evidence or experience. One example is when someone says that all teenagers are irresponsible based only on one bad experience with them as a teenager. It is an unfounded generalization that ignores the reality there are responsible teens. Also, it does not reflect on how many people have had one bad experience with teenagers.
