Miranda warnings: The latest research and its implications

In the landmark case of Miranda v. Arizona1, the Supreme Court of the United States paved the way for a litany of warnings that are familiar to virtually anyone who watches television or attends the movies. Less familiar — to lawyers and judges, as well as to the public at large — is the fact that the specific wording of these warnings was never prescribed by Miranda and varies widely across jurisdictions. Prosecutors and defense counsel alike need to understand how Miranda language can affect their cases and how to obtain and utilize the proper expertise for establishing or questioning the validity of a given defendant’s Miranda waiver.

The legal background

Miranda never mandated that an arresting officer must state, in the following exact words: “You have the right to remain silent. Every word you say can and will be used against you ….” Instead, Chief Justice Warren’s majority opinion called for the use of “clear and unequivocal terms” to convey the various components of this warning,2 adding that a “fully effective equivalent” to the decision’s sample wording would also suffice.3 The Court later confirmed this distinction by supporting the use of “the now familiar Miranda warnings … or their equivalent”4 and by noting with approval that other courts “have not required a verbatim recital of the words of the Miranda opinion.”5

In Massachusetts, the reliability of a Miranda waiver is determined by considering “all of the relevant circumstances surrounding the interrogation and the individual characteristics and conduct of the defendant.”6 In order to judge an interrogation appropriately, lawyers and courts should both identify the actual language used to articulate the Miranda rights and determine the individual defendant’s capacity to perceive, retain and process that specific information. The commonwealth bears the burden of establishing beyond a reasonable doubt that the defendant’s Miranda waiver was voluntary, knowing and intelligent.7 

The research

The leading scientific authority on the linguistic variability and impact of Miranda warnings is forensic psychologist — and
Massachusetts native — Professor Richard Rogers. Rogers and his colleagues have obtained some critical findings in this area:

1. A review of cases from 945 federal, state, and county jurisdictions revealed that 866 different versions of Miranda warnings had been given, ranging in length from 21 to 408 words and demanding a level of comprehension that ranged from the second grade to post-college.8

2. An assessment of 107 defendants with mental disorders indicated that the 25 percent who were most impaired only understood about 24 percent of Miranda warnings, while the 25 percent who were least impaired could comprehend only about 66 percent of these warnings.9

3. An analysis of 121 Spanish translations of Miranda warnings revealed numerous omissions and mischaracterizations, including the absence of such key elements as the rights to silence and counsel, and the presence of “dissimilar content with a substantial trend toward more information in English than [in] Spanish versions.”10

4. A comparison of juvenile and adult Miranda warnings surprisingly found that the juvenile warnings tended to be over 50 words longer, ranging from 52 to as many as 526 words longer than the adult versions, and featuring correspondingly higher required reading levels.11

 

Such findings tend to refute what have been described as common “Miranda myths”: “Everyone already knows the Miranda warnings”; “Miranda warnings are the same wherever you go”; “While Miranda warnings are easy to understand, juvenile warnings are very easy to understand”; and “Miranda warnings delivered in Spanish are the same as those delivered in English.”12 Contrary to these notions, the latest research suggests that attorneys, judges, and experts should examine both the specific content of given warnings as well as any cognitive shortcomings of the defendant.

The evaluation

Developing a comprehensive forensic psychological test to assess Miranda language difficulties across jurisdictions has been problematic. The use of one pioneering group of measures — collectively described in various appellate decisions as the “Grisso Test” or “Grisso Instrument”13 — was hamstrung from the outset by the presumption that “to the best of our knowledge, the wordings which we used are employed identically or with slight variations in most other jurisdictions.”14 As a result, “Miranda research for … two decades implicitly assumed the general uniformity of Miranda warnings.”15 In recent years, these measures have encountered admissibility difficulties in a number of jurisdictions, including New York,16 Connecticut17 and Florida.18

More recently, Rogers and his colleagues have developed and initially validated a Miranda Vocabulary Scale (MVS) that accounts for language differences in the warnings and reflects “key vocabulary words found in Miranda warnings across American jurisdictions.”19 However, there can be no single measure that can function as an “independent, fully comprehensive determinant of a defendant’s state of mind in regard to confession evidence.”20

A properly trained forensic evaluator would seek out the precise wording of the Miranda warning administered in a given case. Initially, the warning should be analyzed to determine the overall level of difficulty it represents, using a Flesch-Kincaid estimate21 or similar methodology. Once the evaluator knows the degree of difficulty presented by the warning, he or she must then assess the defendant’s oral and reading comprehension, using a measure such as the Peabody Picture Vocabulary Test (PPVT4) or Wide Range Achievement Test (WRAT4).

This crucial testing should occur within the context of a full clinical examination that ascertains general intelligence, identifies interfering psychiatric conditions, screens for neuropsychological dysfunction, and assesses the potential for malingering. To place these examination results in context, the evaluator must review whatever treatment, correctional, educational, arrest, employment and other records can be obtained. The evaluator should explore two main questions: has the defendant been exposed to Miranda warnings on other occasions in the past?,22 and do obtained results reflect an ongoing pattern of impairment or do they instead appear to have surfaced all too conveniently at the same time that the defendant was most recently examined?

The forensic evaluator should also conduct an interview that investigates the defendant’s recollection of the nature of the interrogation that produced the Miranda waiver, and whether the defendant was, for example, intoxicated, malnourished or sleep-deprived.23 A competent and persuasive forensic opinion will reflect that the evaluator compared the actual Miranda warnings to the defendant’s individual skills, deficits and mental condition, with particular attention to the same “totality of the circumstances” test as that employed by the legal system for which the evaluation was conducted.24 Overall, “without appropriately broad psychometric investigation, such evaluations are likely to face robust Daubert challenges to admissibility in both state and federal courts.”25

Conclusion

Counsel cannot afford to presume that every Miranda warning employs the same language that we find in countless films and television programs, or even in the Miranda case itself. If the words are different, meaning and clarity are likely to be different as well. Things can become even more complicated when evaluating a mentally ill, cognitively challenged, youthful or primarily non-English speaking defendant. Under these circumstances, counsel may need to procure a comprehensive and competent forensic mental health evaluation in order to raise any doubts regarding the validity of the given warnings. Such considerations are of equal value to prosecutors who seek to underscore the sufficiency of a particular Miranda waiver.
