The Casey Anthony murder trial garnered headlines around the world, not just for the gavel-to-gavel news coverage it received but for the ‘not guilty’ verdict on murder for the death of her daughter, Caylee. Casey was also found not guilty on aggravated child abuse, and aggravated manslaughter of a child. These verdicts were delivered after the presentation of more than 400 pieces of evidence and 90 witnesses during more than 33 days of testimony. The jurors indicated that some of the evidence was irrelevant to their discussion and decision, while others were not compelling. A prosecutor must choose from the evidence collected what they will present to the jury, much like a researcher must make choices when presenting findings. And both must present that evidence in a way that the correct conclusions can be drawn. Public opinion differed significantly from the jury’s verdict. What presentation guidelines can be gained for researchers from this headline story?
