Pat Wertheim attempts to make the comparison methodology fit the steps of the scientific method. He states the second step of developing the hypothesis is that it has or has not been made by the same person as the inked prints.

David Ashbaugh also attempts to make the methodology fit the portions of the scientific method which state the question or problem, and develop the hypothesis. He believes these are presupposed in friction ridge uniqueness and permanence.

He suggests that ACE-V is the scientific method, as it tests the hypothesis by the comparison and verification process of each comparison conducted. The paradigm of single unit friction ridge uniqueness ceases to exist once the three-dimensional aspect is transferred during the deposition of a latent fingerprint to a two-dimensional image.

The presupposition that Ashbaugh relates to in the scientific method has never been subjected to scientific testing. Since the transfer is so relevant to the hypothesis, the ability of the various levels of biological uniqueness to transfer must be scientifically tested to determine what can be reliably used in the application of ACE-V.

The combination of deposition matrix, distortion, and effects of the substrate during the transference process removes the probability of a reliable duplication of single ridge unit uniqueness.

The effects of the processing techniques utilized to visualize the impression must also be considered to determine how detrimental those may be to the fingerprint paradigm of single ridge unit uniqueness. It is a process, which will guarantee precision of application, not accuracy of the conclusion.

In reversing his decision in Plaza, et al, Judge Pollak found that the Daubert factor of testing remained both pertinent and unsatisfied.

Fingerprint FAQ No agency can do everything in every case.

Validation of the premise that a conclusion is drawn from is part of the scientific method that must be established prior to the application of the process.

The process is neither the scientific proof nor the scientific method. The reliance of a fingerprint paradigm based upon a three-dimensional aspect applied to a distorted two-dimensional transfer, without validating the ability for that uniqueness to transfer, will leave one wondering how scientific any conclusion about the transfer impression can be.

Friction skin growing and the snowflake paradigm does not equate to individuality. It is inductive logic, which is: A number of analogies of untested subjective applications, such as two persons who are unaware of their color blindness, can have repeatable outcomes following ACE and Verify their perceptive conclusions inaccurately.

Accuracy is directly proportionate to the amount of testing that the hypothesis is subjected. Constant modification must take place until consistency is reached between the stated or modified hypothesis and the testing results.

Once this consistency is established, then the stated hypothesis becomes a reliable theory.

Friction ridge skin and how it relates to the permanence of fingerprints

Friction ridge skin growth and single ridge unit uniqueness do not equate to all remarkable features of the ridge being repeatable upon transference. The ability for ridge detail to transfer accurately needs to be tested under all aspects of the transfer and the development of latent fingerprints.

It is not scientifically sufficient to compare one inked impression to another to form an opinion of detail transfer that is reliable and accurate.ACE-V 1 - IS IT SCIENTIFICally reliable and accurate?.
