I like debunking, actually I just love arguing. I've listed links to the relevant psychological biases and fallacies along with my responses. In the same way I watched your video, I'd appreciate it if you'd read them and try to understand what they mean and how they apply to thisThanks for the reply![]()
I think we can agree to disagree. What this does is make me suspicious more than anything. The only way to disambiguate is with a rigorous statistical analysis, but I would say the burden falls on the people making paranormal claims to prove that this is not the case.I do not agree with all of your assertions. But firstly, yes they do find it easier to find cases in countries with a belief in reincarnation. These people will be more willing to share their stories and ofcourse more likely to take the child seriously. This would be the case if reincarnation was taking place and if it wasn't. The fact that more cases are reported in these countries does not sway the argument either way. I would actually say that the fact that people who do not believe in reincarnation report having children saying this type of thing is potentially more persuasive of prorenincarnation than the fact that people who initially believe in reincarnation report children saying these things is persuasive against reincarnation. The argument that these people are more likely to be deluding themselves is ofcourse extremely valid.
I completely disagree when you compare the phenomenon to the placebo effect. The mind is extremely complex and powerful and is able to distort and/or create reality but how could the brain implant a series of extremely verifiable facts about an individual that the child has has no (apparent) contact with? Like Dr Tucker says- coincidence in these incidences is 'preposterous'.
I'll handle the statistical argument below, but with respect to the placebo effect, I can think of numerous ways. First, I don't really think it is the placebo effect, just something similar. Maybe the family talked about this person, before they thought the child knew language or when they thought the child wasn't listening, and thus failed to report this to the investigators. Maybe when conversing they led the child to the correct answer unconsciously via body language and facial expression. That is what I meant by cold reading. The parent can lead the child from very general abstract statements to very specific ones, easily and quickly in the same way that fraudulent psychics have demonstrated that they can. In general, people see patterns everywhere and see causation where there is only correlation, its really no surprise.
Here's an explanation of cold reading, I would look at the section titled "subconscious cold reading" and check out the references listed for it.
http://en.wikipedia.org/wiki/Cold_reading
I agree that Dr Tucker is wrong to say that the families have nothing to gain from it. But a lot of these cases occur with people who have no inclinations towards this type of thinking. It would be strange for them to suddenly think this to make themselves feel better. Although there is always the possibility. Doubtful though for all these cases.
These are unsophisticated people in rural India and Sri Lanka. They are very ready to believe, superstitious, and know absolutely nothing about how science should work. They see a couple general details or specific details and fill in the rest. The biases in perception smooth out any rough edges, and these people's biases are stronger than most.
In psychology, this is called confirmation bias:

Your assertion that because the have only a few hundred cases (+2,500 to date) this implies that the phenomenon cannot be real because there are billions of people, I feel is silly. The obvious objection to what you said is that perhaps they have a small team? Perhaps these cases are hard to find? Perhaps reincarnation is a rare event and usually people do just die? Your rationalisation there is not, to my eyes, rational.
I think you misunderstand what I'm saying. If you flip an unbiased coin a number of times there are going to be patterns in the results, where it goes HTHTHTHT or HHHH.... whatever. If you only look at those subsequences of the overall sequence of results you will see patterns there, the only way to learn that the pattern is actually random is to look at the statistics of the whole sequence. If you flip the coin billions and billions of times It will happen a whole lot. If I have a team of people that just search the sequence of coin flips, big or small, they're going to find tons and tons of patterns. Plus, people are wired to see these patterns.
What they really need to do is follow a single community, or population, one that is suited to their available resources. If they can't catch all the cases, they must be able to say what percentage of the cases they do catch. Then they must take into account the huge wealth of psychological and mathematical data available to generate an estimate of how often these cases will occur by 'chance' or more 'chance+bias'. If the number of cases they find, corrected for their accuracy of detection, is higher than a conservative number expected number, by greater than the statistical error, then they'll have a reasonable claim, not proof, but a claim that the scientific community can debate.
So if :
detected/detection_rate > error + predicted
Then they might have a claim worth listening to, although there will still be a lot of wiggle room.
Right now these experimenters are searching a sequence of flips for patterns, They claim the expected number of patterns is zero, when they say that "the cases cannot be coincidental" and compare that to the number they found. This is just not a credible way to do science. I assure you there are tons of cases where this has happened that they've missed, statistics demands it.
Here are some relevant links:

http://en.wikipedia.org/wiki/Correlation_does_not_imply_causation
Er the last paragraph you wrote... cultural bias is not a factor in many of the cases and even if there were cultural bias (which there is) this does not disprove his claims. It only makes them less credible.
I'll say it again, extraordinary claims extraordinary evidence.
Right now they don't even have ordinary evidence.
