Is Wikipedia a good Encyclopedia to consult? WARNING, Please READ!

No.  It is NOT Academically vetted.  Anyone can edit its content.  It is therefore not academically sound.  It is best to consult the Encyclopedia Britannica.  Do not settle for something that is from a suspect source.  The editors of Encyclopedia Britannica are seasoned academic personnel who research, carefullly, the facts and theories and knowledgebase of all human development.
