Numerous studies show that elephants are among the most intelligent species on the planet. They pass the mirror test, a test for self-awareness that is also believed to correlate with empathy. They display altruistic behavior for other elephants (and sometimes humans as well). They appear to mourn their dead and even perform death rituals. There is lots of scholarly research on the topic. Seemingly, it is the perfect research question: "Do elephants have emotions?"
...Until I realized midway through my preliminary research that almost nobody disagreed with the fact that elephants had emotions. This surprised me greatly—in all my other studies, there were plenty who claimed that no animal could feel true, human-like emotions, and that those who claimed otherwise were guilty of anthropomorphism. However, I could not find a single instance of any expert singling out elephants as not having human-like emotions. That meant that I had nothing to argue against—I would be writing nothing more than an "info dump".
So, I once again changed my topic, this time to...

I'm not doing a broad "fish intelligence" or "fish emotions" paper; instead, I'll be writing about the possibility that fish feel pain. This is an important topic because it, more than anything, affects how humans interact with fish—most prominently, the way we fish. If impaling fish in the mouth and pulling them out of the water to suffocate becomes known to actually cause them pain, angling would definitely become a major moral problem. I will not be asking "Should angling be outlawed?" or making something similar my research question; my question will simply be "Do fish feel pain?" (From my research so far, it seems I can pretty much generalize this question across all fish species.) However, I will certainly mention the moral issues in the paper.
A good thing about this research is that it's very divisive—neurological experts disagree pretty evenly. I should note that unlike most of my previous research topic ideas, I have no initial opinion on the issue at the start—I don't know which side I'll ultimately argue for. This blog post is getting pretty long for me to go any further, but I'll discuss some of my findings in future blog posts.
