I get some strange answers to this one as well... in a recent 1 on 1 with one of our favorite YT guru-guys I was told specifically to target people with the title first and foremost. Make it interesting, intriguing and clickable. That went against what I believe (and what Andrew is saying above); that titles should first be searchable.
Regardless of what school of thought you subscribe to here is the bottom line with titles:
1) Whatever tag you put in the beginning of the title is going to act as a sort of 'master tag.' So if you really want to target one specific keyword for the purposes of search that is something you are going to want to do.
2) The value of search only goes so far; you can get a million impressions but if it isn't interesting people aren't going to click on it.
So in synopsis; utilize your title for search but also make it interesting. For further reference on the subject I suggest looking into the AP Stylebook. This outlines specific ways that journalists word titles in order to grab the most attention (while also being informative). Sorry there wasn't a more clear answer to this question, good luck!
