What is anecdotal evidence? It is the attempt to surmise a generality (e.g. a trend) from just a few data points. These are collected typically by an individual via experience and/or observation, often over time. From this evidence, one tries to make suppositions about the general reality.
One might ask why this would need to be done? Why is not the truth of how things are just disseminated for all to learn from and use in their daily life? Well, it turns out that various groups claiming authority often have agendas, or are not particularly bright, or both. As such, they don’t necessarily provide the straight-up situation. That is where you come in. It is up to you to try to figure out the reality.
Anecdotal evidence can be tricky. From a statistical perspective, you probably never have enough data collected to be able to declare a trend. Gathering enough data is what authorities are supposed to do, and often they don’t want to do it on purpose. Anyway, often you might notice a trend; for example about how the ladies operate.
You might believe that the trend is true, but probably you should be a bit of a skeptic. Ask you self various questions. Are there other explanations for what I think that I am seeing? Am I seeing all of the data, and perhaps ignoring some data? Am I just trying to confirm what I want to believe? You get the idea. You really need to do this because what one person can see in the world might be a bit smaller than what is required.
So after some careful analysis, do you think that you have a trend/generalization? If so, maybe discuss it with others that that you trust. Then, there is always the test of time. Did it stand up to that?
