parkade2   Gavin de Becker in his book The Gift of Fear is about how we sometimes short circuit the information we receive from the environment.  Here is an excerpt regarding a seeking help in a situation and concluding with how social dynamics really bollocks things up for women.

   “A woman alone who needs assistance is actually far better off choosing someone and asking for help, as opposed to waiting for an unsolicited approach. The person you choose is nowhere near as likely to bring you hazard as is the person who chooses you. That’s because the possibility that you’ll inadvertently select a predatory criminal for whom you are the right victim type is very remote. I encourage women to ask other women for help when they need it, and it’s likewise safer to accept an offer from a woman than from a man. (Unfortunately, women rarely make such offers to other women, and I wish more would.)
  I want to clarify that many men offer help without any sinister or self-serving intent, with no more in mind than kindness and chivalry, but I have been addressing those times that men refuse to hear the word “No,” and that is not chivalrous—it is dangerous.
When someone ignores that word, ask yourself: Why is this person seeking to control me? What does he want? It is best to get away from the person altogether, but if that’s not practical, the response that serves safety is to dramatically raise your insistence, skipping several levels of politeness. “I said NO!”
  When I encounter people hung up on the seeming rudeness of this response (and there are many), I imagine this conversation after a stranger is told No by a woman he has approached:
MAN: What a bitch. What’s your problem, lady? I was just trying to offer a little help to a pretty woman. What are you so paranoid about?
WOMAN: You’re right. I shouldn’t be wary. I’m overreacting about nothing. I mean, just because a man makes an unsolicited and persistent approach in an underground parking lot in a society where crimes against women have risen four times faster than the general crime rate, and three out of four women will suffer a violent crime; and just because I’ve personally heard horror stories from every female friend I’ve ever had; and just because I have to consider where I park, where I walk, whom I talk to, and whom I date in the context of whether someone will kill me or rape me or scare me half to death; and just because several times a week someone makes an inappropriate remark, stares at me, harasses me, follows me, or drives alongside my car pacing me; and just because I have to deal with the apartment manager who gives me the creeps for reasons I haven’t figured out, yet I can tell by the way he looks at me that given an opportunity he’d do something that would get us both on the evening news; and just because these are life-and-death issues most men know nothing about so that I’m made to feel foolish for being cautious even though I live at the center of a swirl of possible hazards DOESN’T MEAN A WOMAN SHOULD BE WARY OF A STRANGER WHO IGNORES THE WORD ‘NO’.”
  Whether or not men can relate to it or believe it or accept it, that is the way it is. Women, particularly in big cities, live with a constant wariness. Their lives are literally on the line in ways men just don’t experience. Ask some man you know, “When is the last time you were concerned or afraid that another person would harm you?” Many men cannot recall an incident within years. Ask a woman the same question and most will give you a recent example or say, “Last night,” “Today,” or even “Every day.”
  Still, women’s concerns about safety are frequently the subject of critical comments from the men in their lives. One woman told me of constant ridicule and sarcasm from her boyfriend whenever she discussed fear or safety. He called her precautions silly and asked, “How can you live like that?” To which she replied, “How could I not?”
  I have a message for women who feel forced to defend their safety concerns: tell Mister I-Know-Everything-About-Danger that he has nothing to contribute to the topic of your personal security. Tell him that your survival instinct is a gift from Nature that knows a lot more about your safety than he does. And tell him that nature does not require his approval.
  It is understandable that the perspectives of men and women on safety are so different—men and women live in different worlds. I don’t remember where I first heard this simple description of one dramatic contrast between the genders, but it is strikingly accurate: At core, men are afraid women will laugh at them, while at core, women are afraid men will kill them.”
