    While science and pseudoscience both explain things, only science can be used to predict new things that have not previously been seen. Maybe this is the difference.

    Hi Jason, no I was agreeing it was correlation definitely NOT causal. The only causal portion would be the frequency of interaction with people on motorcycles & tattoos who might then increase or uncover the pre-exisitng desire for these deviant behaviors through some form of peer pressure or desire to fit in. (Yes, I called tattoos and motorcycles deviant) I have no tattoos, but do love riding motorcycles, although I gave it up.

      When you do research in the behavior of organisms, you get these things called interaction effects. The tattoos may interact with the organism's risky behavior tendencies and provide more opportunities for risky bike riding, thus, leading to or causing more accidents. Again, correlation do not necessarily mean causation; however, correlation does not exclude causation. And tattoos may not be sufficient enough alone to cause more accidents with some organisms. The scientific relationship gets complex, though, when you are studying biological organisms.

    Correlation does not imply causation. The absence of evidence is not the same as evidence of absence.

      Kevin, perhaps people who do more daring things (ride fast on motorcycles, ride while intoxicated, etc) are also more likely in general to do more daring things to their skin. In other words, what causes them to get into motorcycle accidents is completely independent of the tattoos. For example, if tattoos ceased to exist or the tattoos were removed from these bikers, the lack of tattoos wouldn't decrease the number accidents any more than putting tattoos on a person who hates risky behavior would increase bike accidents for that person. After all, correlation does not mean causation. You are implying a causal link. Specifically, tattoos cause more bike accidents. How? Tattoos increase the contact with bikers and the number of invitations to ride. Again, correlation does not always mean causation.

      I put my reply above by accident. Yes, my assertion was the personality will attract both types of behaviors.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
