Speaking as an epidemiology geek, it is far more likely that the forum members are not representative of the sample of Lucid owners so that the incidence and prevalence of drivetrain issues on this forum are not representative of what‘s actually being seen across all Lucid owners. There are only a few instances where the rates seen in forum members would be the same as the whole owner set. Here are a few:
* The issue is universal or near universal so that underlying characteristics won’t matter.
* The issue is vanishingly rare, so that the differences are just rounding errors.
* A Lucid owner joining the forum is entirely a random event, so that the set of forum members is a random and representative cross section of the entire ownership set. However, we know this to be non-random, as people who seek out online forums to post have different backgrounds and motivations than normal owners.
* Finally, there is the issue of underreporting bias: Consumers with extreme positive or extreme negative experiences with a product are more likely to post about them. However, in this case, people with extreme negative experiences (e.g., drivetrain failure) are the only ones who post. So far, except for
@hydbob, no one with a positive drivetrain experience has posted about it. So, short of a poll and preferably one with equal incentives for those with negative and positive experiences to respond, you won’t get an accurate picture from this forum.
