The more you research a specific topic the worse Wikipedia seems as a source. For a general overview before writing a paper and starting real research? It’s great.

For actually researching and compuiling that paper? Terrible. The Wikipedia editors are people too and they cant know everything.

I love Wikipedia and have donated and will donate again but looking back on it there’s a reason that most schools don’t let you source it as Wikipedia and make you look at the actual sources that Wikipedia uses.
