Yes, it will have such behavior, but it won't *incentivize* such behavior - which I hope will make a huge difference!
Personally I don't just zap posts that make me smile; I also zap the ones that make me think and ones that deepen/broaden my understanding of something.
 

 It’s not about zaps. It’s about just tried to explain from the nature prospective. I wish that happiness and positivity will prevail but it’s hard! 

 If I'm understanding you - and maybe I'm not - I don't think positivity will necessarily prevail overall in Nostr, but I think anyone who wants it to prevail in their feed can do that. 

 That’s will be a hard ratio but I hope this gonna be the case 😉
