Jury Selection Bias, Voir Dire, and Building Better Juries
How much does jury selection actually affect the outcome of a criminal trial?
In this episode of Andrew & Andrew on Texas Criminal Defense, Andrew Herreth and Andrew Decker review an extensive research paper from Southern Methodist University examining bias in jury selection across Dallas County felony courts.
The conversation covers unconscious bias, racial demographics, jury questionnaires, Batson challenges, jury participation rates, and practical voir dire strategies that every criminal defense lawyer should understand.
Rather than debating abstract legal theory, Andrew and Andrew discuss what the data may mean inside a real courtroom and how trial lawyers can become more intentional during jury selection.
Whether you're a practicing criminal defense attorney, prosecutor, law student, or simply interested in how juries work, this episode provides an excellent introduction to one of the most important—and least understood—parts of a criminal trial.

Frequently Asked Questions
What is voir dire?
Voir dire is the jury selection process during which attorneys and the court question prospective jurors to determine whether they can fairly apply the law to the facts of the case.
The purpose is not to educate jurors or persuade them—it is to identify bias, determine challenges for cause, and select a fair jury.
Why is jury selection so important?
Because jurors ultimately decide the facts.
The same evidence may be viewed differently depending upon the experiences, beliefs, and perspectives of the jurors selected to hear the case.
Effective jury selection helps ensure that jurors can fairly evaluate the evidence rather than relying upon preconceived beliefs.
What is unconscious bias?
Unconscious bias refers to automatic assumptions, experiences, beliefs, and perceptions that influence decision-making without a person even realizing it.
Everyone possesses unconscious bias.
The challenge is determining whether those biases prevent a juror from following the law fairly.
Should criminal defense attorneys use jury questionnaires?
Many experienced trial lawyers believe so.
Written questionnaires may:
encourage more honest responses;
save courtroom time;
identify sensitive issues privately;
improve voir dire by allowing attorneys to ask better follow-up questions.
Andrew and Andrew discuss how Dallas County judges have incorporated questionnaires into felony cases and why more courts should consider using them.
What is a Batson challenge?
A Batson challenge alleges that a party exercised a peremptory strike based upon race or another constitutionally protected characteristic rather than a legitimate, race-neutral reason.
The hosts briefly discuss Batson and note that it deserves an episode entirely devoted to the topic.
Should lawyers thank jurors for answers that hurt their case?
Yes.
Andrew Herreth explains that he thanks jurors for honest answers because truthful responses allow attorneys to identify bias and preserve peremptory strikes for jurors who truly require them.
Rewarding honesty encourages more candid discussions throughout voir dire.
