UPDATE (Wednesday, Nov. 26, 12:30 p.m. ET): Has Bill Cosby’s staunch refusal to address the ever-increasing allegations illustrating a decades-spanning pattern of drugging and raping women damaged his public perception?

If the results from a new survey are any indication, this mushrooming scandal has dealt a devastating blow to the once-beloved star’s public image.

According to The Wall Street Journal, a new survey undertaken by a research firm that ranks perceptions of celebrities indicates just how far Cosby has fallen; once the third-most trusted celebrity in the firm’s database, Cosby has now sunk down to #2,615.

The survey also ranks Cosby’s value for commercial endorsements, an arena in which the former Jell-0 pudding pitchman once ranked fifth. Nowadays, Cosby now comes in at a dismal #2,476,

In addition, a social-media analytics firm found that Cosby was the subject of 700,000 comments on social media during the first 20 days of November, and about a third of those comments expressed a negative opinion about the star.

The author of an authorized biography about Bill Cosby now concedes that he should have included charges of sexual abuse first brought to light a decade ago.

In a column in The New York Times, David Carr criticized Mark Whitaker for omitting these earlier charges from his book, Cosby: His Life and Times, noting that four different women had gone public with similar allegations while Whitaker was writing the book. “Any book of the size and scope of Mr. Whitaker’s should have gone there,”; wrote Carr.

Whitaker initially claimed he “was aware of the allegations, but ultimately decided not to include them in my book,”; citing what he characterized as a lack of “independent witnesses and no definitive court findings.”;

However, after Carr’s article, Whitaker admits he was wrong, responding to Carr via Twitter: “David, you are right,”; Whitaker tweeted on Monday. “I was wrong to not deal with the sexual assault charges against Cosby and pursue them more aggressively.”;  Whitaker also added that he has been “following new developments and will address them at the appropriate time. If true, the stories are shocking and horrible.”;
