Well it's not really straight compliments like 'you're funny, or you're pretty, or you're smart' that I value the most. I appreciate it if there is more to it, otherwise I'm liable to dismiss it. But saying that, my INTP does compliments so rarely they all sound genuine.
From other people, compliments make me very uncomfortable. I begin wishing for the ground to open and swallow me, anything to get out of the hell of having to react and respond. (My dad constantly chides me about the necessity of receiving compliments gracefully instead making some deprecating remark. argh. thank you daddy, can I die now?)
But back to my INTP Here are some examples I have enjoyed:
"You make me not want to talk to anyone else"
"I love it when you wear that dress"
"I love talking to you"
"What do you think about X?"
"When I read your book... it's amazing. I don't know how you do it"
"You feel right"
"Would you look at this and give me your opinion?" (about something he's working on)
"You have such a natural beauty"
"Sometimes you care too much" (not in a harsh way)
I have learned to see the compliment in the way he treats me. The intellectual respect, consideration, selflessness, unveiling of his mind and curiosity of mine, willingness to let me see his emotions, playfulness... it's completely different than I've seen him treat anyone else. In this, I receive unvoiced compliments every day.
