Turns out hearsay can be pretty reliable.
The validity of secondhand information about President Trump’s dealings with Ukraine reemerged as an issue at Wednesday’s impeachment hearings. The president’s supporters initially dismissed the whistleblowers’ revelations as unreliable “hearsay.” They are now making the same claim about the State Department diplomats who were first to testify.
This as virtually everything the whistleblower reported has been confirmed by those in the loop or present at the events in question.
That result would line up with the findings of an analysis of two million whistleblower complaints filed at more than 1,000 private companies. Kyle Welch, a business professor at George Washington University, had just published a study in September using 13-years of information from a firm that makes and runs corporate compliance software. His research, with Stephen Stubben of the University of Utah, is producing much needed data about the nature of whistleblower complaints.
So, when hearsay became an issue in the impeachment investigation, he decided to run some numbers on it.
The surprise: Secondhand “reports are 47.7% more likely than firsthand reports to be substantiated by management, which suggests that management views many secondhand reports as credible.“
