Getting back to Dean's original question on whether rebirth is karma-deterministic or not:
In cognitive neuroscience prediction, randomness, probability, are all major research topics -- there are many aspects of the data we can study about the mind and brain that involve these ideas, including ranging from something sometimes called 'ballistic' in the sense of basically automatic and highly predictable, to other functionality that appears nearly random, freedom of choice, etc. There's a lot of mathematical modeling involved (aka computational neuroscience).
If we take the idea of reincarnation seriously, i.e., not just as a cultural artefact, but something that might be 'real' in the western scientifically-oriented sense (i.e, just as 'real' as the Indo-Tibetan traditions consider it), then all sorts of interesting research questions come up, and Dean's original question would be central to these.  A couple of such questions might be: a) Could an incarnating person be somehow capable of choosing parents/family specifically, or would there inevitably be a certain degree of randomness or unpredictability involved, perhaps mathematically akin to modeling and predicting the weather?  b) What might be the criteria for an incarnator to be capable of choice, or, rather be deterministically/ballistically driven by prior karma?

Dear Matthew,
It all goes back to the Abhidharmakosabhasya. See AKBh on AK 3.15ab, 
but Pradhan's edition has a lacuna here. Therefore:
dLVP, vol. 3, p. 50.
Best wishes,
Eli
