and need to be replicated in real world situations to really assess the usefulness of them. They show great promise that weapon focus effect and be counteracted by education on the topic, but they will remain theoretical until further research and implementation of the idea can be conducted. One method that has become more and more prevalent to reduce negative consequences that can stem from errors in eyewitness testimony, including errors that can arise from weapon focus effect, is expert witness testimonies by research psychologists about eyewitness testimony. This is an educational session, which a judge has to allow, given by a forensic psychologist to a jury as part of the trial. This form of expert testimony has been called social framework testimony, defined by Cronin as "expert testimony that presents conclusions based on social science research to assist the court in making a decision." The expert testimony would provide the jury with a context for evaluating eyewitness testimonies and the jury is meant to factor that into its decision making process. These educational sessions in the courtroom will help make the presentation of eyewitness testimony as rigorous as possible and put as much scrutiny on the social evidence as what is put on physical, scientific evidence. Eyewitness testimony is very often wrong, and the scrutiny put on it greatly reduces the number of false convictions. The major problem with this strategy is that many judges do not allow this expert testimony in their courts. For example, in the court case Blasdell v. State (2010, 2015) a woman who had been robbed at gunpoint by an unknown man was able to describe the gun in great detail but could only provide very imprecise details of the perpetrator. The defense was unable to present expert testimony on the concept of weapon focus and the suspect was convicted based on the eyewitness testimony. Despite cases like these, reasoning behind judges not permitting expert testimony is Their reasoning is usually that they think what the social framework testimony will present is common knowledge. However, the data overwhelmingly shows that the typical jury member does not know most of the information presented by the expert. The fallibility of eyewitness testimony is not common knowledge and eyewitness psychology can offer valid and constructive information to juries. Even with this knowledge, jury decisions cannot perfectly serve justice without exceptions, but perfection in the legal system is
