A probabilistic formalization of contextual bias in forensic analysis: Evidence that examiner bias leads to systemic bias in the criminal justice system

  title={A probabilistic formalization of contextual bias in forensic analysis: Evidence that examiner bias leads to systemic bias in the criminal justice system},
  author={Maria Cuellar and Jacqueline A. Mauro and Amanda Luby},
Although researchers have found evidence contextual bias in forensic science, the discussion of contextual bias is currently qualitative. We formalize years of empirical research and extend this research by showing quantitatively how biases can be propagated throughout the legal system, all the way up to the final determination of guilt in a criminal trial. We provide a probabilistic framework for describing how information is updated in a forensic analysis setting by using the ratio form of…

The role of prior probability in forensic assessments
The contentious issue of whether forensic scientists, when asked to provide evidence that will be used to evaluate various competing propositions about physical evidence, should consider the prior probabilities that those propositions are true is examined.
Public Beliefs About the Accuracy and Importance of Forensic Evidence in the United States
Recent advances, especially the use of DNA technology, have revealed that faulty forensic analyses may have contributed to miscarriages of justice. In this study we build on recent research on the
Likelihood Ratio as Weight of Forensic Evidence: A Metrological Perspective
A rebuttal against the possible perception that a single number, such as the Likelihood Ratio, can provide an objective, authoritative or definitive weight of evidence is provided.
Letter to the Editor — The Bias Snowball and the Bias Cascade Effects: Two Distinct Biases that May Impact Forensic Decision Making
Seven different potential sources of bias are presented, including innate sources relating to the mere fact that the authors are human, general sources that emerge from the experience, training and environment in which forensic examiners operate, and also the specifics of the case being investigated.

Bayesian Hierarchical Random Effects Models in Forensic Science
A project (SAILR: Software for the Analysis and Implementation of Likelihood Ratios) was funded by the European Network of Forensic Science Institutes through their Monopoly programme to develop a software package for use by forensic scientists world-wide that would assist in the statistical analysis and implementation of the approach based on likelihood ratios.
Rate of false conviction of criminal defendants who are sentenced to death
Using survival analysis to model this effect, it is estimated that if all death-sentenced defendants remained under sentence of death indefinitely at least 4.1% would be exonerated, which is a conservative estimate of the proportion of false conviction among death sentences in the United States.
Investigating the 'CSI Effect' Effect: Media and Litigation Crisis in Criminal Law
Beginning in 2002, popular media disseminated serious concerns that the integrity of the criminal trial was being compromised by the effects of television drama. Specifically, it was widely alleged
