Ask HN: Why do most of my questions go un answered on HN?

Several of the questions have good discussions that can be found using search. Overall, I'd say that your questions have had above average responses relative to the volume of submissions that arrive at Hacker News, the topics the ask about and the total number submitted.

Generally, questions where it seems that the topic is important to the author personally and the topic is one on which HN can bring expertise rather than preformed arguments will tend to do better.

I think you'd get a better response if you put some more time / effort into the questions. For example, summarize the research into the topic that you've already done in your question.

Questions that are commonly discussed or too generic "what's your favorite productivity hack?" etc often get glossed over for those reasons.

Try asking something really specific and making it easy to answer, reducing the burden of doing most of the work for a commenter.
