All forces are just mathematical models invented by humans.
"Fictitious force" is just an unfortunate name choice. It gives people the wrong idea that some forces are more "real" than others. But that is just philosophy, irrelevant to physics. That is why I prefer the terms "inertial forces" and "interaction forces".
Yes, I read this word "inertial" a lot on the Wikipedia link provided by rcgldr.
Can you explain this notion ?
