As you note, this was written in 2012. Have you looked for more recent research into lie detection? As well as fMRI and polygraph, there’s voice stress analysis, non-verbal cues, microexpressions, and cognitive interviewing. I did a brief search a while ago but couldn’t find anything particularly accurate. I would be extremely keen to hear about any methods with high sensitivity and/or specificity, or with the potential to achieve that in the near future. I might be willing to pay someone a modest amount to review the evidence and predict when accurate techniques will become available, and/or to recommend the best existing method (or combination or methods).
