“The differences in layout can render an exhibit either informative
or misleading,” Rychlak writes. “For that reason, court proceedings
subject exhibits to a determination of whether they are probative or
merely prejudicial.” Rychlak is MDLA Professor of Law and associate
dean for academic affairs at the University of Mississippi School of
Law.
No similar standards govern the visuals used in the global warming
debate. Climate change alarmists often misrepresent data, misleading
the public and describing a “reality” unsupported by science. Visuals
have been used, for example, to make minuscule increases in temperature
or greenhouse gas emissions look dramatic, or to make polar bears
appear “stranded” on ice floes. Such tactics do little to further the
process of honest inquiry, Rychlak notes.
“If we are to make wise decisions, we have to understand the
evidence,” said Rychlak. “However, as words can be misused by an
advocate, charts, graphs and even photos can be misused by their
creators. This can lead to confusion in a time when clarity is
essential.”
