1. A computerized method of analyzing a plurality of hypotheses based on evidence and analyzing diagnostic strength of evidence, comprising: receiving, by a computing device, one or more a plurality of hypotheses and one or more pieces of evidence; determining, by the computing device, whether the one or more plurality of hypotheses are competing or non-competing based on the one or more pieces of evidence, where the one or more pieces of evidence has a corresponding source; if the plurality of hypotheses are competing: receiving by the computing device, an evidence confirmation value for each of the plurality of hypotheses for each of the one or more pieces of evidence, determining, by the computing device, an evidence contribution value of each of the one or more pieces of evidence to confirming or disconfirming each of the one or more plurality of hypotheses, each contribution value is based on all of the evidence confirmation values, determining, by the computing device, a diversification index based on all of the evidence confirmation values and the contribution values, the diversification index is a measure of a degree of distinction in each of the one or more pieces of evidence, determining, by a computing device, a diagnostic strength value for each of the one or more pieces of evidence based on the contribution value, determining, by a computing device, a diagnostic strength value for each of the one or more pieces of evidence based on the contribution value, and graphically displaying, by the computing device, for each diagnostic strength value on a display device; and if the plurality of hypotheses are non-competing: receiving, by a computing device, for each of the one or more pieces of evidence corresponding to the plurality of hypotheses that are non-competing, an evidence credibility score that is determined independent of a reliability of the corresponding source to produce consistent results, and an evidence reliability score that is determined based upon the reliability of the corresponding source to produce consistent results, determining, by a computing device, a veracity score for each of the one or more pieces of evidence corresponding to the plurality of hypotheses that are non-competing based on the evidence credibility and reliability scores, and graphically displaying, by the computing device, at least one piece of evidence from the one or more pieces of evidence, at least one hypothesis from the plurality of hypotheses, and a link between the at least of piece of evidence and the at least one hypotheses, the link showing a corresponding determined veracity score on each diagnostic strength value to a display device.
