The near-daily tide of sexual misconduct allegations against famous men has spawned a head-turning stream of apologies, acknowledgments that experts say have been generally self-serving and aimed at the public more than the victims.

The apologies have often seemed obligatory, as the men offer excuses for their behavior or cast doubt on their accusers, experts said.

“They’ve been awful,” psychologist Harriet Lerner said of the public apologies.

So what makes a good apology?

In its best form, an apology is a direct acknowledgment of a wrong, and it eases the distress of the wronged party, said Cindy Frantz, a professor of psychology at Oberlin College who has studied the apology.

“What we found is if people don’t feel heard and understood, the apology is not effective,” Frantz said. “They need to feel the perpetrator gets what they did and understands how it impacts the victim. They need to feel genuine remorse.”

So that means no excuses about being drunk, lacking impulse control or any other justification that deflects blame.

A genuine apology says:

“I get it, I screwed up, I was wrong, your feelings make sense, and I want you to know I won’t do it again,” Lerner said. Then it includes making reparations that fit the wrongdoing.

Certainly, when the allegations are true, any apology is better than none at all. And an apology can be especially tricky territory for the wealthy and famous who are trying to avert lawsuits or ruined careers. Even so, in nearly every case, the apologies have fallen far short, experts said.

Let’s take a look at some of them.

Charlie Rose

TV talk show personality Charlie Rose is the latest to be accused of groping and unwanted sexual advances. His then 21-year-old former assistant said he used to walk around naked and call her to talk about his sexual fantasies.

In a statement, Rose said he didn’t think all the allegations leveled against him by eight women were accurate but felt he “was pursuing shared feelings” and now has “a profound new respect for women and their lives.”

Analysis: “Rose’s apology, like most of the others, focused primarily on him rather than on his victims,” said Guy Winch, a New York-based psychologist, author and public speaker who specializes in relationships. He added that Rose’s mea culpa includes an “actual apology,” which many others did not.

Sen. Al Franken (D-Minn.)

Franken says he doesn’t have the same memory his accuser does of an off-set rehearsal in which she says he put his tongue in her mouth, a response that casts doubt on her account.

Analysis:Winch said Sen. Al Franken also offered an “actual apology” for mock-groping a woman’s breasts while she was asleep, which was captured in a photograph and was his idea of a tasteless gag at the time.

Harvey Weinsten

Weinstein, accused of raping and assaulting women, has denied rape allegations but said he knows his behavior has caused pain. In his apology, he said he would seek a therapist, then pivoted and said he was going to channel his anger to fight the NRA. He also said: “I so respect all women.”

Analysis: Lerner, author of “Why Won’t You Apologize?” said movie executive Harvey Weinstein and actor Kevin Spacey have offered “faux apologies.” He said many in the recent wave of apologies appear to have a sense of entitlement.

“They are crafted so fans can say, ‘What do you want? He apologized,’ ” Winch said. “They are not crafted with the idea of owning what they did.”

Kevin Spacey

Spacey, accused of groping young men and teens, announced he was gay when actor Anthony Rapp accused the “House of Cards” star of making an aggressive advance toward him more than three decades ago, when Rapp was 14. Spacey’s tactic seemed a thinly veiled attempt at changing the subject, experts said.

Analysis:Lerner said Weinstein and Spacey don’t make the cut as heartfelt apologies. “One doesn’t need to be an apology expert to recognize apologies that are slippery, vague and devoid of accountability,” she said.

Glenn Thrush and Dustin Hoffman

New York Times reporter Glenn Thrush, accused of unwanted sexual advances toward young journalists, said he had been drinking too much. Hoffman, accused of sexually harassing a former intern, said in part, “I feel terrible for anything I might have done that could have put her in an uncomfortable situation.”

Analysis: The apologies that have been splashed across the news in recent weeks are more geared toward the men keeping their reputation and fan base intact than at making amends with the victims, according to experts.

Louis C.K.

C.K. has admitted to masturbating in front of young women in professional settings, which he has acknowledged was irresponsible because of the power he had over them.

In his statement he said: “Now I’m aware of the extent of the impact of my actions. I learned yesterday the extent to which I left these women who admired me feeling badly about themselves and cautious around other men who would never have put them in that position.”

Analysis:In his apology, the comedian went further than most in accepting responsibility, naming his victims and attempting empathy. What he should do now, Winch said, is apologize to them personally and try to help them, and other women, in their careers.
