I guess the consensus is we're talking about the physical grabby-smacky side of self-defense, yes?
Teach them a few basic striking techniques (such as punch, backfist, front kick, palm strike etc) that they can remember easily, some basic blocks, nothing too fancy or complicated.
I feel that teaching someone to punch is likely helpful, assuming it's more of a boxing cross than anything else, something powerful and relatively intuitive, but still, I would speculate that they're probably more likely to mess up their wrist, open their knuckles, get shocked by the pain, and piss the guy off than knock him out or stop him dead.
I'd skip the backfist too, I can't see someone learning a backfist, learning to derive any sort of power from it, and managing to burn it into their brian so they remember to do it in time.
I'd replace a front kick with an heel stomp type kick to the knee/instep. Simpler, easier to learn, more intuitive, not going to land you on your butt, and something that is a heck of a lot easier to generate power with.
Palm strikes to the face, definitely. Assuming you can somehow get them to remember to do it.
As far as teaching blocking, yeah it would be nice, but I've seen a lot of students, and I don't think I've ever seen ONE who could execute a block against a committed attack after 8 hours of training. Maybe against the gigantic hay-making blows that you supposedly get attacked with on the street (the phrase should really be, "in your living room"), but I can't say I've ever seen a hay-maker like that outside of martial-arts self-defense and Hollywood Western Saloon Fights.
Just to be clear, RTDK, I'm definitely NOT saying your approach is ineffective. I can't come up with anything different, except for swapping out techniques for ones that *I* happen to like more. I'm not doubting you or your theory, I'm doubting the ability of the average uncoordinated person with a heavy flinch reaction to actually suck it up and USE what advice and skills you would have given them. Again, I'm not trying saying you're wrong, I'm saying that you'd probably do about the best that could be done, but that the best that can be done in 8 hours is pretty negligible.
I teach/study under/play with martial artists, primarily. But, with friends/family, I have on occasion been talked into showing them "some moves they can do for self-defense." Sure, show them that palm strike, show them that wrist-grip escape. Practice it with them in a controlled way. Teach them whatever you want. Then say, "ok, now I'm going to swing at you with this hand, like this, and then grab you in a bear hug. Use what I've showed you to defend yourself." Swing slow, and grab gently, but make sure it looks like it has intent, make sure you're really driving in close, and I can almost guarantee that the result will be a combination of patty-cake flailing and flinching away, and/or stumbling backwards. The problem in slef-defense teaching is not (mainly) the material, but someone's ability to perform the material.
We can probably all know some technique or other which WE OURSELVES can pull off, that most martial artists around us can't, whether it's a hick kick with power that is fast and controlled enough that you never get thrown with it, whether is a complex wrist lock that you can actually pull off in sparring, or some wire-fu-esque flying kick from a prone position that actually seems to function. We've all got our own tricks that most people can't pull off. However, there's a huge array of things that everyone we train with can all do; low kicks, various punches and hand strikes, basic grappling, rudimentary ground fighting; most martial artists have a basic knowledge of most of these things. We practice them for hours, every week, every month, for years. But, if we remember when we started, we remember than getting off a decent punch under duress was once as difficult and seemingly unachievable in practice as your buddy's flying scissor kick now seems. To someone walking into a self-defense course, that punch at an attacker is STILL just as difficult.
I've definitely seen a lot of inexperienced people, even teens and adults, get panicked or emotionally overwhelmed during sparring, maybe cry or start to hyperventilate... I'm sure you've seen it yourself.
Exactly. Everyone's seen it, and it's the other side of what makes teaching self defense so tricky.
I'm going to agree here. Mindset.
It's easy to teach a well-trained martial artist self-defense responses/technique/systems/theories/whatever it is. They've had years to get used to being hit. They've had years to get used to people being in their face, being on top of them on the ground, grabbing them. They've had years to ditch the turn-your-head-and-flinch-away response, so when someone crashes into them, their reaction is not curl up and cover the head, but something more proactive. They probably, deserving or no, think they're pretty lethal, and they've had years to form that belief. They've had years to learn to move, to react, and how to do so. They've had years to realize that anything they learn needs to be drilled and experimented with and perfected and tested.
So yes, you can take them for 8 hours and show them a couple concepts, and have them walk away safer. Heck, you can take a well-trained Martial-Artist for 30 minutes and probably give them something useful.
As far as the untrained... They haven't had years to get used to the idea and feel of an aggressor, and they aren't going to go home and train what they learn in those 8 hours. I'm not saying it's not possible, but whatever it is certainly isn't going to be a serious of wrist-grab break-aways, takedowns, punches and eye-pokes. Maybe some of that can be part of it, but I'll just say that most of the "self-defense" I've learned or seen is stuff that probably works great for someone who practices it diligently and has a background to build from.
I've never taught a self-defense course, and I doubt I ever will. I can train people in martial arts. That's something I understand, something I know how to do, but in Martial Arts, you can spend 8 hours teaching someone the basics of a classical reverse punch. I can teach someone a super-simple system of barraging alternating palms to the face, rakes, and elbow strikes, coupled with intermittent knees and low kicks. Teach that to a martial artist, and they'll probably do a decent job of banging-up any angry boyfriend that tries to hurt them. Teach it to your girlfriend and make her practice frequently, and she'll probably do a pretty good job beating YOU up! Teach it to someone off the street who's natural response it to curl up in terror and then never see them again? I don't see that working too well.
I'm not saying that short self-defense courses can't work, just that I've never seen one which seemed very viable. Back to mindset. Sure, with the right mindset, you probably don't NEED a self-defense course. Having played around with a variety of martial artists and completely untrained friends and friends of friends, and inebriated friends of friends who just like to pummel, I'm willing to bet that the most valuable self-defense technique is an inborn sense of aggression. So yeah, those with an aggressive and violent reaction to being grabbed, struck, etc. will probably do just fine, with or without the self-defense. Those without, those with a more subdued mindset, will not do well either way.
Take a bunch of people resigned to dealing with violence, who see violence somewhat regularly, who have a job which constantly reminds them of violence, and who may very likely take it upon themselves to practice dealing with it occasionally, train them for 16-40 hours and give them a refresher every year or so, and I have no doubt that they will be able to do better than they would otherwise. Grab that 16 year old with a nervous personality who spends their days at school, hanging out and chatting, and staring through a computer screen, give them the same run-through and expect it to help them out 3 years later when their roommate's boyfriend tries something unpleasant and I doubt that the course will do much, no matter how intuitive or effective the material.
But, if we're touting a self-defense course, it should work for pretty much ANYONE, yes? If I could teach anything as self-defense, it would be a natural aggressive response to violence. But I don't know how to teach that.
---------------------------------------------
Finally, the last part of why I am NOT a fan of many self-defense courses. Many are built to fight martial artists in a controlled situation. For example, the guy who starts in a stance, throws an unbelievably huge, slow, flailing punch to the head from three feet away, and then stands still, punching arm extended, as you block (yeah right) and execute whatever eye-gouge or knee strike is prescribed. Or slightly more realistically, a defense system which relies on someone who attacks like a sport-fighter, from a distance, in a fighting stance, with clear strikes and attacks. Perhaps useful for the guy who encircles you with his biker gang and says, "put-em up," but...
In my experience, the people who are abusive or physically aggressive are NOT the people who train to fight. My best guess is that anyone with the self-control to really learn a fighting style, probably has the self-control, and hopefully the respect and human decency not to smack their girlfriend off the fridge. Thus training to fight trained fighters is NOT the best use of an 8 hour course. What is the best use, I do not know.
