Beyond a Reasonable Doubt - podcast by Davidhorn

What shapes an investigator's mindset — and does it matter more than their training? In this episode, Dr. Ivar Fahsing speaks with Ahmet Demirden, criminal justice academic and former Toronto Police Service officer, about the psychology behind investigative interviewing practice.
Drawing on two decades of experience across Canada, Turkey, and international training contexts, Ahmet Demirden introduces regulatory focus theory as a lens for understanding why officers interview the way they do — and why knowledge alone is rarely enough to change behaviour.
The conversation covers the gap between training and performance, the role of organisational culture and required drivers, the legal complexities of the Turkish inquisitorial system, and the emerging potential of AI and simulation technology to provide the feedback mechanisms that policing has long lacked.

Dr Ivar Fahsing speaks with Dr Julia Korkman — psychologist, researcher, and one of the leading voices in legal psychology in the Nordic region — about what investigative interviewing looks like in Finland: what works, what doesn't, and why the gaps matter.
In this episode:
- Why human memory is the core material of criminal justice — and why so few professionals are trained in it
- How the desire to help children speak can introduce the very errors it's meant to prevent
- The Kailinna wrongful conviction case and the cost of confirmation bias
- Cultural humility in cross-border and multilingual interviews — from Finland's sauna culture to collective societies in Southeast Asia
- What a nationwide survey of Finnish police officers revealed about knowledge of interviewing methods
- Why Norway's shift to recording succeeded — and what Finland can learn from it
- How AI is being used to generate alternative hypotheses in child abuse investigations
- Remote hearings, automated transcription, and the future of technology in investigative interviewing

Every major interviewing framework - PEACE, KREATIV, ORBIT - distils to the same essentials: stay nice, ask good questions, and listen.
So why does confession-driven culture remain so deeply embedded, even in systems that have formally adopted investigative interviewing?
In this episode of Beyond a Reasonable Doubt, host Børge Hansen speaks with two leading members of iIIRG - the International Investigative Interviewing Research Group - about what actually makes reform stick, and what keeps pulling it back.

Denmark implemented investigative interviewing standards in 2015, yet officers were convicted of coercion in 2021. Thomas Skou Roer reveals why and what's next.
In this candid and thought-provoking episode of Beyond a Reasonable Doubt, host Ivar Fahsing speaks with Thomas Skou Roer, associate professor at University College Copenhagen and former Danish criminal detective with 18 years of service, about the complex realities of implementing investigative interviewing standards in Denmark—and why having good standards doesn't guarantee good practice.

What does it take to implement investigative interviewing across an entire nation's criminal justice system? In this episode, recorded in Hua Hin, Thailand, Dr Ivar Fahsing speaks with Ms. Santanee Ditsayabut — senior prosecutor at the Office of the Attorney General of Thailand and Director of the Secretariat of the Nitivajra Institute — about Thailand's landmark efforts to embed ethical, evidence-based interviewing practices across its justice system.
Santanee shares the story of Thailand's PEACE Program Informity: a multi-year, multi-agency initiative bringing together prosecutors, police, special investigators from the DSI, judges, and officers from across government. She speaks candidly about the challenges of changing practitioner mindset, overcoming the myth that investigative interviewing is too time-consuming, and the critical role of policy-level support in sustaining real change.
The conversation explores how Thai cultural values of respect and dignity align naturally with the ethos of ethical interviewing — and how understanding memory science and cognitive bias transforms the way practitioners approach evidence gathering. Santanee also discusses the important role of judges in evaluating evidence accurately, and why legislative reform may be needed to support long-term implementation.
The episode marks a historic milestone: Thailand is certifying its first national PEACE trainers and champions, positioning the country as a leader in investigative interviewing across Asia.
