EG: They change the title to something that 'gets clicks' then change it to something that 'blends in'

I don't think so. In my case at least.
Imagine a user typing Brand Brand or Brand Brand.com (because they seem to google even easier names these days). Would the user click if the results returns "Keyword Keyword" in title?

I know most user don't look at the URL, so this could cost me some traffic. i.e. users shaking their head thinking where is "Brand Brand".

I'm tempted to change the title to "Brand Brand" only, but I'm after another "keyword keyword" I keep in the title.
