We find the defendant....

"We find the defendant...innocent!  [whisper]  I mean, not guilty!" If you’ve ever heard the jury foreman give a jury’s decision, you’ll notice that they never say the defendant is “innocent.” Instead, they’ll conclude that the defendant is “not guilty.” Although the terms may sound interchangeable, “not guilty” and “innocent” actually mean two different things. “Not guilty” is a legal conclusion, whereas “innocent” means the person didn’t commit the crime. For example, think of O.J. Simpson. In a court of law, he was found “not guilty” of killing his ex-wife – but if you ask the majority of Americans , they’ll tell you he’s not innocent.

When we say that “not guilty” is a legal decision, we mean that it’s a decision based on criteria described by laws – namely in the U.S., if the prosecutor can convince the jury of the defendant’s...

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...

Doing psychological research with police: A chat with Lorraine Hope

Will and Timothy are joined by guest Dr. Lorraine Hope, for a chat about doing research with the police. 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 ExE chat! Today we’re happy to be joined by Dr. Lorraine Hope to talk about her research. Lorraine is a psychology professor at University of Portsmouth in the UK, and does quite a wide range of psych law research. Most relevant to our chat today, she’s done work with police officers in the UK – both improving their practices, as well as conducting research. So really taking some of the research we talk about on this blog, and applying it to real world situations to see if it works. Lorraine, thanks for joining us...
