What is the difference between 看来， 看起来， and 看出来 ？
Obviously, this is a tricky one.

I know these three phrases have some same words and looks no differences for foreigner, but they are very different! If I give you one example for each phrase, you still will get confused when you meet a different one, so I'm gonna show you how to fishing instead of just give you a fish, in another word, master those three 'bastards'.

看来: mean looks like or seems. This phase usually stand for an quick and dramatically attitude change, like it or not doesn't matter. Example: "I told you so (我告诉过你)." the other person most likely say "looks like you are right. (看来你是对的)"  despite that he/she didn't want to admit it. Or he/she admit it after learned by his/her own experience, example: "the lung exam show there are cancer cells in there, looks like I should quit smoking. (肺部检查显示那里有癌细胞，看起来我应该戒烟)"

看出来: mean figure out, get some results. I give you some thing, some entity, some person, some question, some being, some creature, some machine, you look closely, study, research, do stuff, and I come back, ask you "你看出来什么门道儿了吗？(Did you figure out something yet?)", it means I want get some results, some answers from you, those information go in and through your brain, you process them, and you need to produce something, give some output.

看起来, mean (it/he/she/thing) looks like or seems. When use this phrase, it means whatever the subject or object is, it usually not taking too much effort, or no need to get a closer look, or a deep digging, the answer is easily observed from the appearance of object or direct message from the subject/matter. Example: "It looks like our suspect's get away car just get away without him." "看起来我们嫌疑犯的逃脱车没带他就跑了。" and there is one more, in the US movie/television show, when a cheating scene get caught, the character usually say "it(thing) is not what it looks like." you shouldn't translate or express in Chinese with "这(件事)并不是看起来的那样。", because this is better "这(件事)并不是看上去的那样。", there you go, you just learn another one.
