More than a third of people believe flirtatious women are partly responsible for being raped, a survey has found.
The poll of 1,000 men and women also found more than 25% believe victims are partly to blame if they have worn revealing clothing or been drunk.
Amnesty International UK, which commissioned the survey, said the findings were "truly shocking" and showed the Government's policies on tackling rape were failing.
A spokesman said the findings should act as a "wake-up call".
"The poll also reveals the scale of public ignorance of the unacceptably high number of women raped every year in the UK," she said.
Jenny Watson, acting chairwoman of the Equal Opportunities Commission, said: "There still seems to be an assumption that women are sexually available, so if a woman has gone out to have a good time, then she must want to have sex."
Sheila Coates, the director of South Essex Rape and Incest Crisis Centre, said victims - who often blame themselves - are reflecting the blame they can face from society.
She said: "Most women who contact us will say, 'This was my own fault'.
"That's the mirror of what goes on in a court case. While we have juries who are uninformed, we're going to have rapists set free to do it again and again."
The Home Office said it has changed the law to try to improve conviction rates.
"We have made a number of changes to the legal system and to how the police and Crown Prosecution Service work, to put victims' needs first and to make it easier for cases to get to trial and secure convictions," a spokesman said.
