When investigations go wrong – in science and policework

A story of both a wrongful conviction and scientific fraud We’ve talked about many of the ways police investigations can go wrong, including mistaken eyewitness identifications , memory errors , and false confessions . Often, when people imagine police investigations running afoul, they imagine egregious cases in which police plant evidence or physically torture suspects to get them to produce confessions they know are false. Although situations like that do occur, mistakes in investigations require no intentional wrongdoing. A detective doesn’t need to be trying to get a false confession, for instance, in order to get one ( as our guest writer Fabi Alceste has written about) . Errors happen often without the investigators realizing anything has gone wrong. Similarly, when people imagine bad scientific research happening, they often imagine scientists fabricating data or committing outright fraud. Scientific fraud is a problem, but it’s quite rare. However, there are many questio

You have the right to remain silent....unless you are free to leave

Guest post by Fabiana Alceste. “You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford an attorney, one will be provided for you.” These words have likely been burned into our collective consciousness by the ubiquitous and fantastic TV series Law & Order (in my case, Law & Order: SVU). These words are often spoken as Olivia Benson and Elliot Stabler handcuff the main suspect of the episode—the last words trail off as they walk offscreen and the show cuts to a commercial break. We know this scene, and we know the words…but why do these warnings exist and for whom are they intended? Benson and Stabler are ready to make the arrest! But first they need to inform the suspect of their Miranda Rights According to the U.S. Supreme Court, custodial interrogations are sometimes characterized by the use of police intimidation, trickery or other psychological tactics, a

An international collaborative replication study

Will and Timothy are joined by guest Dr. Mario Baldassari, for a chat about an international collaboration to replicate a previously published study. In this chat format, we gather regular authors and guests in Slack and have a moderated conversation, guided by prompts and questions selected in advance. Participants get to respond to each other's points, make comments, and ask each other questions in real-time. The transcript has been lightly edited. Will Crozier &#x1F419 Welcome to another Exercise in Exceptions chat! Today we’re joined by Dr. Mario Baldassari to talk about an issue that isn’t directly related to psych and law, but science in general. Mario was recently a part of a team that did an internationally collaborative replication – that is, a large team of researchers across the world ran a previously-published psychology study, to see if it still worked (or how far the effects generalized). Big international collaborations that produce repl
