Foreword

As I have reflected periodically over the 32 years that I have spent working in ‘the law’, it has become increasingly apparent to me how ill‐equipped I was to deal with many aspects of my practice. I was a guineapig for the Bar Vocational Course, a newly designed course for would‐be barristers which was intended to and achieved a fundamental shift away from teaching law and practice to teaching the practical or vocational skills required within the core domains of a barrister’s work: interviewing clients, conference and negotiation skills, written advocacy and oral advocacy. And, when I began to work as a second six‐month pupil, then as a junior barrister, then as Queens (now Kings) Counsel and latterly as a High Judge assigned to the Family Division, I appreciated the vocational skills that I had learned and put my manuals to good use.

But the longer I worked in the law, the more I realised that all my formal studies had not addressed a subject that was fundamental to my work and more importantly to doing that work well: human behaviour in all its different forms and potential relevance. As a junior barrister doing drunken‐driving cases, licensing applications, whiplash claims and defective good claims, my shortcomings in understanding human behaviour were easily masked. However, as I tip‐toed into the territory of more serious crime, in particular sexual offences and into child abuse and parental conflict, the need to understand human behaviour became ever more apparent.

Much of what we do in the law is about determining what happened and who did it. We immerse ourselves in the ever‐increasing paper and electronic detail (digital footprints are now of ‘Bigfoot’ proportions) to prove facts about times, dates, what was said, by whom, to whom, in what language, who did what and in what sequence. In family law, we very often ‘Fact Find’, and the whole of our justice system is rooted (even in inquisitorial family proceedings) in a binary process in which most cases are resolved by one side proving (beyond reasonable doubt or on balance of probability) that some ‘event’ occurred. If it is not proved, then the law treats it as having not happened. In that sensory overload of detail directed at proving a fact occurred or that it did not occur, what may be the most illuminating issue of ‘why?’ is very often overlooked. How often I have listened to questioning of witnesses that only addresses the facts of whether he was the abuser or she was making it up. And, yet only a moment’s reflection shows how limited a perspective that brings to the questioning, to the evaluation of the answers, to the process of fitting various pieces of the forensic jigsaw together and to the judges’ ultimate decisions about what happened. How do you evaluate facts without some understanding of the human beings who undertook those actions, without some understanding of what has shaped that person into the individual they were at that moment, without some insight into what may have been spurring their behaviours or impacting on their ‘recollection’ or on their ability to give evidence or reliable evidence. And, the more complex, unusual, bizarre, inexplicable or serious the behaviours, so some insight into the person’s functioning can become more critical and more illuminating. In my field whether it is understanding which of two parents may be more likely to have come to fatally injure a child or to understanding whether an abused mother may be able to successfully separate from her abuser, whether a perpetrator of abuse has the capacity to change, whether a child can be rehabilitated to her parents care or the impact on an individual’s ability to give evidence or reliable evidence or a multitude of other issues, the benefits of an understanding of human behaviour and psychological functioning are incalculable.

The analysis and prediction that a Case Formulation or Risk Assessment may provide is capable of filling that gap in the understanding of legal professionals and judges. Insight into why an individual might be unable to recall matters one might expect them to recall or to have admitted to doing something they did not or even could not have done may make the difference between a life‐altering decision going one way or another to a parent being labelled a child abuser and children being placed for adoption or not. An accurate psychological evaluation which considers response to crime, understanding of triggers and empathy with a victim may make the difference between an offender safely being released and rehabilitated and a potentially dangerous recidivist roaming the streets looking for his next victim. The currency of that concern in the light of the murder of Zara Aleena who worked here in the Royal Courts of Justice could not be greater. An understanding of the individuals and the research underpinning alienating behaviour may provide a family court judge with a perspective inaccessible otherwise.

The authors of the chapters in this book have deep knowledge and experience across a range of fields and provide a window for the uninitiated, inexperienced through to the highly experienced into a host of fascinating fields of practice in human behaviour and which give a tantalising hint of the potential benefits of a deeper immersion into those waters.

It seems to me that the value in a book such as this is precisely that it enables to reader to dip a toe into many different psychological waters and thereby to acquire at least an insight into the possibilities that an expert in the field of psychology might bring to a wide range of different legal areas of practice. The chapters which consider issues such as ethnic and cultural considerations and assessments of learning‐disabled individuals rightly draw attention to some of the very particular issues which may impinge both on behaviour itself and what we bring with us in terms of expectations of cultural norms but also on how one approaches assessment in such circumstances.

The test for granting permission to instruct an expert and for the admission of expert evidence in the courts in the Family Courts is that it is necessary to determine the proceedings justly, which represents quite a high bar. In Re H‐L, the then President of the Family Division said that necessary lies ‘somewhere between indispensable’ on the one hand and ‘useful’, ‘reasonable’ or ‘desirable’ on the other hand, having ‘the connotation of the imperative, what is demanded rather than what is merely optional or reasonable or desirable’. It is rare in a case involving human actions (as opposed to contract or tax or construction) that the court will not find psychological insight useful and desirable, but we have decided that the test is necessary. Necessity to resolve justly involves an interactive value judgment – psychological evidence may promote a just outcome, but delay may inhibit it, and so although the evidence itself might be ‘necessary’ from an evidential perspective, other matters such as the need to reach a conclusion swiftly may outweigh that evidential necessity with a child welfare necessity.

That being so, books such as this provide us with some insight into an area we are unfamiliar with and which might sign‐post us to more reading or which might equip us with some knowledge on which to advocate or evaluate the necessity of expert evidence in a case and thus enable us as judges to deliver better (because more informed) decisions and ultimately to deliver decisions which are more closely aligned with the true best interests of children or more congruent with the objective ‘truth’ underlying the human behaviours which underpin the case.

Expert evidence can be invaluable to the courts and parties. In the Family Justice System, we have experienced considerable problems in ensuring that the pool of experts willing to help us is sufficiently deep and wide and in my role as Chair of the Family Justice Council Committee on Experts, we have been doing a lot of work since the launch of the report of the President of the Family Division Working Group Report to implement solutions to the wide range of barriers which impede ‘experts’ offering their expertise to the Family Court. Whilst there can be no substitute for the evidence of an objective and conscientious expert in an individual case, the authors of this book enable us all to gain some insight and understanding into a range of areas of psychological practice which will I think add real value to our collective understanding of the human behaviour which underpins so much of what we do.

1Psychologists as Expert Witnesses

Leam A. Craig, Hugh C. H. Koch, and Gus A. Baker

Introduction

The use of expert witness testimony in courts is not new, with reports of expert witnesses being used since the 14th century (Wigmore 1978). Although not reported to have been the first psychologist to give expert witness testimony, Professor Hugo Münsterberg was one of the first to document psychological evidence in the courtroom in his publication On the Witness Stand: Essays on Psychology and Crime (1909). Since then, psychologist expert witnesses have regularly been used to provide expert witness testimony in cases such as criminal trials, child protection and family proceedings and personal injury cases (Wilcox and Craig 2018).

There is no definitive legal definition of an expert. It is a matter for the court to rule upon in each case. However, the Legal Guidance (prepared by the Crown Prosecution Service for England and Wales) defines an expert as: ‘a person whose evidence is intended to be tendered before a court and who has relevant skill or knowledge achieved through research, experience or professional application within a specific field sufficient to entitle them to give evidence of their opinion and upon which the court may require independent, impartial assistance’ (Crown Prosecution Service, Disclosure Manual, 2021).

In the appeal court hearing of Brian Wilson and Iain Murray v HMA [2009] HCJAC 58, where three prominent clinical and forensic psychologists gave evidence as to the reliability of confessions of murder made during police questioning and to the presence or otherwise of suggestibility, Lord Wheatley ruled on the standards of expert witness evidence. ‘Firstly, the subject matter under discussion must be necessary for the proper resolution of the dispute, and be such that a judge or jury without instruction or advice in the particular area of knowledge or experience would be unable to reach a sound conclusion without the help of a witness who had such specialised knowledge or experience. Secondly, the subject matter in question must be part of a recognised body of science or experience which is suitably acknowledged as being useful and reliable, and properly capable of reaching and justifying the opinions offered, and the witness must demonstrate a sufficiently authoritative understanding of the theory and practice of the subject. The nature and scope of expert opinion evidence cannot at any one point in time be exhaustively defined’ (Wheatley 2009, HCJAC 58). Here, Lord Wheatley is referring to both the application and scientific rigour of psychological theory and the ability of the expert witness to explain psychological theory relevant to that case: that the witness has specialised knowledge or experience and that the evidence or tests used are part of a recognised body of science or experience. As Lord Wheatley observed in 2009, ‘…the bare ipse dixit of a scientist, however eminent, upon the issue in controversy, will normally carry little weight, for it cannot be tested by cross‐examined nor independently appraised, and the parties have invoked the decision of a judicial tribunal and not an oracular pronouncement by an expert’.

An expert witness is someone who has specialist knowledge, rather than years of experience post qualification, something which is also highlighted by the Crown Prosecution Service (2010). The Crown Office and Procurator Fiscal Service (2021
