Don't be surprised if that blockbuster Senate hearing on the charges against Supreme Court nominee Brett Kavanaugh today ends with no blocks being busted.

It's entirely possible that both sides believe what they are saying - and that there won't be any definitive conclusion to be drawn from the day's testimony.

Human memory just isn't up the challenge of letting us reconstruct past events in accurate detail. That's the view of psychologist Elizabeth Loftus, who is a leading expert on memory.

When I called her yesterday at the University of California, Irvine, where she is a professor, Loftus said the greatest misconception about memory if that "it's like a recording device."

"That isn't how it works," Loftus said. "Memory is subject to fading. It's subject to contamination."

Cory Booker's certainly is. I emailed Loftus a copy of my piece last week about a column the senator wrote for his student newspaper in 1992. In it he discussed how he made an awkward attempt at seducing a girl when he was in high school.

Booker described how he had a line from the Tom Cruise movie "Top Gun" going through his head as he made his move. One problem: The incident happened in 1984. The movie didn't come out until 1986.

"This is just absolute proof of something memory scientists have been saying for years," Loftus said. "When you reconstruct the past, you take bits and pieces of experiences from different times and places and integrate them together."

She recalled that what she thought was her own earliest memory was also debunked by a movie.

"For years and years, I always thought my earliest memory was when I was 4 or 5 and I went to see 'The Greatest Show on Earth,'" she said. "Later I found out that I was 8 when it came out."

Loftus first came to fame in the 1990s, when he was a leading debunker of the panic spreading across the country about alleged sex-cult members who were abusing children at day-care centers.

All over the country, people were being convicted of various sexual offenses based on memories from alleged victims. Some of the alleged perpetrators even convinced themselves they had committed crimes of which they were later cleared.

Dorothy Rabinowitz of the Wall Street Journal won the 2001 Pulitzer Prize for her role in debunking the panic. Central to her reporting was the work of Loftus in her 1994 book, "The Myth of Repressed Memory: False Memories and Allegations of Sexual Abuse."

Loftus did a number of experiments that showed how fallible human memory can be. Her research showed it was relatively easy to implant in an adult's mind a memory of being lost in a mall or rescued by a lifeguard as a child.

Once a false memory takes root, she said, it's impossible to distinguish it from a real one.

When it comes to the allegations that Christine Blasey Ford made about Kavanaugh, she said, the committee should look into long gap between the alleged incident and their first mention by Ford.

Loftus said she read the affidavits filed by four people with whom Ford said she discussed the incident, and key questions remain.

"When did she attach the name Brett Kavanaugh to it?" she asked. "Her husband affidavit is very ambiguous. It insinuates she said the name in that 2012 therapy session, but he doesn't assert it."

Loftus said she also has questions about a second accuser who first came to light in a New Yorker piece by Ronan Farrow. That's Kavanaugh's Yale classmate Deborah Ramirez, who said he exposed himself to her at a party.

Farrow first made the news during his mother Mia's messy custody fight with filmmaker Woody Allen. Ronan supported his sister Dylan in her assertion that Allen molested her when she was 7. Another son, Moses, supported Allen in the fight, which ended without Allen being criminally charged.

Loftus said that Farrow is supposed to be acting as a neutral journalist but his personal views might color his reporting.

"How is he questioning people?" she asked. "How is he shaping the memories of the people he talks to?"

Don't expect answers to those questions. Ramirez won't be testifying before the committee.

Nor will a third accuser who recently was unearthed by Michael Avenatti, the lawyer for Stormy Daniels who has said he might run for president in 2020. That woman accused Kavanaugh of being present at parties where gang rapes occurred. (Though the dates don't match up.)

As it now stands, Ford will be the only witness against Kavanaugh. I expect she will be every bit as convinced of the truth of her testimony as Booker dsfffconvinced that he remembered quotes from "Top Gun" two years before it was made.

Barring some dramatic last-minute bombshell, it will be Ford's memory against Kavanaugh's memory. Then it will be up to the Senate to sort it out.

That should be memorable.
