#104 Belief is the Death of Reason with Dr. Nathan Hall and Dr. Paola Tiedemann

In this episode, Dr. Nathan Hall and Dr. Paola Tiedemann discuss their research on canine detection applications and the use of olfactometers. They explain that olfactometers are scientific instruments used to provide measured and standardized odors to animals. The researchers have been working on miniaturizing olfactometers and making them more rugged for various applications. They also discuss the merging of technology and dogs, predicting that within a few years, cameras and olfactometers could be used for initial dog training. They also explore the importance of the handler-dog relationship and the potential for technology to provide confirmation of the dog's findings. In this part of the conversation, Cameron and Paola discuss the importance of unifying the protocols and procedures used in scent detection. They emphasize the need to consider variables such as the length of time, collection methods, and the type of container used. They also discuss the plausibility of dogs remembering scents in real-world environments and the challenges of training dogs to match samples with different variations. They touch on the impact of factors like stress, medication, and age on human scent and the need for further research in these areas. They also highlight the importance of training dogs on a variety of targets and distractors to improve their ability to generalize and avoid false positives. Finally, they discuss the challenges of introducing new samples and variations in training and the need for ongoing evaluation and testing. In this final part of the conversation, Cameron Ford and Nathan Hall discuss the importance of challenging and critically evaluating detection dog training methods. They emphasize the need for accurate and informed decision-making in operational scenarios. They also explore the impact of odor concentration on a dog's ability to generalize and detect targets. The conversation then shifts to the research on firearms detection, including the significance of gunshot residue (GSR) and the volume of odor. They discuss the challenges of training dogs on different concentrations of odor and the importance of training on the actual weapon rather than just the powder. Finally, they touch on the ongoing research on ghost guns and the need to understand the odor profiles of 3D printed firearms.
