In The Case for Forensic Polygraph Testing in Post-Adjudication Sexual Offender Examination and Management, polygraph expert witness Ken Blackstone writes:

Scientifically based studies have concluded that the carefully administered, “forensic” or single-issue (one relevant issue) polygraph exam, conducted properly and optimally by a qualified examiner, is 89 to 92 percent accurate. It is the most accurate tool available today for determining truth or deception. When any reduction from the disciplined rigors of forensic polygraph examination occurs, the reliability of the results can and must be called into question.

However, in the post-adjudication sexual offender setting, a less rigorous “utility” approach is often taken and the accuracy of polygraph results diminishes for a number of reasons. The training, skills and discipline of the examiner are typically lower; the purpose of the examination may be far different and more exploratory; the questions are more generalized, ambiguous, and sometimes confusing. The accuracy of a 91% accurate exam is now 50-50.

In Guaranteed Maximum Contracts construction expert witness Paul Gogulski explains the the G-Max contract:

Still another advantage of G-Max occurs when work must start ahead of final drawings. There are often issues that delay completion of the drawings and therefore start of construction. The G-Max format allows owners to minimize risk when proceeding with work ahead of final drawings. It has been my experience to start work on 30 percent completed drawings while obtaining a G-Max price for the entire project based on preliminary drawings and outline specifications. That’s an extreme example, but it does happen.

In The Case for Forensic Polygraph Testing in Post-Adjudication Sexual Offender Examination and Management, polygraph expert witness Ken Blackstone writes:

In a post-adjudication setting a convicted or committed offender is expected to take periodic polygraph examinations to encourage candor and discourage any lapse or relapse during treatment and supervision. The use of the polygraph in the evaluation and management of convicted and committed sex offenders is of great interest; treatment providers will often agree that the polygraph is the only existing tool for measuring behavior and supervising officers see the polygraph as a way of keeping offenders accountable. A periodic post-adjudication polygraph examination in the community can be used to assess a variety of issues that may include precursors to a reoccurrence and whether the convicted person should be considered for early release of parole or a relaxation of probation controls. These post-adjudication situations are similar in that these examinations will seldom address a specific “issue at hand” and while they are an option the only other option is prison.

In Speaking English is Key to Safety construction safety expert witness Paul Gogulski, BSCE, PE, writes:

Effective communication is a key ingredient of every construction project and is particularly vital in regard to safety issues. Practically speaking, the current policy of promoting bilingual languages as a social-engineering enterprise across a broad spectrum of the nation has a negative impact on the frequency of accidents in the construction industry. The many recent deaths in Las Vegas construction is a grim demonstration of this fact.

OSHA’s general-duty clause states that every employer will furnish a safe place of employment to each employee “free of recognized hazards.” How many more construction accidents will it take to demonstrate that when a contractor’s personnel cannot speak English, a “recognized hazard” already exists?
