He actively promotes the fact that human error is a post-event classification, and that if we are to improve diving safety, we need to understand why it made sense to those involved and to be less judgmental when it comes to incidents and accidents. He has presented at numerous international diving conferences, many times to standing room only audiences, on human factors, human error and an improved safety culture in diving.
