There are a few whiskies that I like because I have a bias in their favor. Not sure I can tell anymore if they are really good or not. Sazerac Rye is one of them, and so is Evan Williams 1783. To some extent Old Granddad is that way. I know what to expect and expect that it will be familiar, and therefore I know beforehand that I will like it.
In like manner, there are some whiskies that I do not like because of a bias. First among these is Basil Hayden, even knowing that it is basically Old Granddad at 80 proof. Taste is not something about which it is useful to argue, but still, one can discuss one's taste, and sometimes influence another's taste in whiskey. And, one's palate can and will change.
As to Basil Hayden, I may never get over my unreasonable dislike of that whiskey. Put some in a glass and don't let me know what it is and I might even like it.
