Which do you think is more dangerous?

brilliant question ! I think half knowledge is most dangerous. normally stupidity may not always leads to a bad state.

Aren't they the same thing? Because if a person only has half the knowledge...then that person would be stupid to the things not known. Hence, only half knowledge and stupidity is the same thing. Hmm...you have me on this one. ha ha :)

"Little knowledge is a dangerous thing.' I agree totally that half or little knowledge can be deadly in many regards. I work in a hospital and each day I come across so many ppl who with half knowledge do some scary things that you would be scared to know. It could be as bad as stopping medicines altogether to altering the dose themselves to prescribing own medicines and stuffs like that. So the consequences of half knowledge is deadly and many a times irreversible.

half knowledge is much more dangerous. one might be too confident to boast on the little knowledge he knows and when asked for a detailed information, he will not be able to give it. he'd just embarrass himself.

Half knowldge is somewhat riskier, I think, because people tend to be or to get cocky, thus taking more risks when they think they "know" enough, while they don't know even half of enough ;) TheFortunes

I do think for stupidity is more dangerous than half knowledge or inproficient or craven. Because 'stupid' does mean for inability to learn. Once people or human cannot do learning, many things will jeopardized their own and others life.

I think half knowledge because is important to know the whole story and not just some knowledge about something. We usually jump to conclusions when we don't know the whole story.

no half knowledge is the riskiest as tht is the situation when one can fall in trouble or there are chances of developing misconceptions among the ppl..to cite a exmaple, my friend is active on mylot n her Bf is nt aware abt all this sites actaully he is iliterate abt computers as he is very much in his work throughtouth the day ...so he ahs half knowledge abt these things so when evr my friend uses mylot n her bf is around he thinks tht she is chatting with unknown ppl n stuff like tht this has lead to arguments many a times now she ahs completely stopped using internet or else she was asked to quit the relation...
