I don't think it's a HD/LD thing. As we've seen and discussed here before, every R seems to have one "fixer". The fixer is the one who puts the most effort to improve the R. In most cases, they simply are more motivated than the other. The HD link comes into play because repressed sexual desire is one heck of a motivator!
But there are LD "fixers" here, too. Their motivation isn't for sex, but for other things such as EC, non-sexual affection, companionship, etc. In fact, most M and R books are purchased by W (fixers), although statistically they are sexually LD compared to their H.
This BB population is disproportionately HD fixers. That's why it seems that all LDs are "lazy" compared to most of the posters here. But I don't think that holds true in RL and not even with some LDs here.
IMO, self-discovery/disclosure is more a function of maturity than anything else. I read somewhere that people generally don't begin "working on themselves" until they approach 40 years of age. I don't know if that's true or not, but it's more important to me now than when I was in my 20s. Of course, that's because I thought I was nearly perfect then.
It would be great if your generalization were true, though. That would make a neat little package, and would include your assumption of good will. I normally think in those terms and have to work to keep from it.
