"I just have zero confidence in said algorithms."
So, you're essentially throwing away all evidence to the contrary, then? It seems like you're saying, "I can see that these websites work. But they won't work for me. Because, although I admit that they have very advanced algorithms for matching people that seem to work, I am an outlier totally alien to their systems. They can never match me, I am the most unique of all humans!"
One thing you might want to factor into your analysis is that most people that use these dating websites probably describe themselves as socially inept (like yourself - no offense). Otherwise they would go out into the real world to talk to people.
Also, in another appeal to your rational side, you are working off of an incredibly small dataset for this entire conversation.
I honestly don't know why I'm arguing with you on this. Maybe it's because I hate to see my friends resign to failure with no reason to do so. We might all die alone, but no one should live alone.
