Past Life Regression

[Alex]

Even if reincarnation is real, it is statistically unlikely than any individual person now living had a string of previous lives, so if, as some claim, the success rate (in properly conditioned subjects) is more than 80% where do those lives come from?

When hypnotized and told to connect to an earlier life why is that result evidence of real events when being hyponized and told to act like a chicken (or Diana Ross) is not evidence that one was once a chicken (or Diana Ross)?

If it is just a parlor game, are the charlatons who do charge for it unethical?

If it is well established that hypnosis can be used to create strongly held false memories (most famously in discovering "repressed memories" of childhood sexual abuse and alien abduction), why is that not a more likely answer for recovered memories of past lives?
