The Dark Side of Peer Review

Remind you of anything?

Peer review is intended to act as a gatekeeper in science. If working researchers deem a paper fit to be published, it should mean that the research is sound, rigorous, and accurate. But an experimental analysis of peer review suggests that peer review might also end up rejecting high-quality material. The analysis points to high levels of competition as the source of the problem.

Jeff Gonzales: Barriers to Learning

Jeff Gonzales of Trident Concepts:

There are many ways people learn, but that is not the real issue. The real issue is a barrier that prevents a student from learning. There are all types of barriers, from lack of motivation to lack of interest and what I have noticed over the years is the importance behind the “why” in training. I don’t get too wrapped up these days about specifics of how I teach. Don’t get me wrong, there is a hell of lot of time in the organization and management of our curriculum. What I find more important is helping the student to understand why they are doing something or more importantly why the need to do something differently…

Working With Disabled Students

The NRA’s Disabled Shooting Services has a “Disability Awareness” document about working with disabled students. (For those not on the firearms side, the NRA is primarily a training and shooting competition organization.) There’s some gun-specific stuff in there, but it’s mostly practical info applicable to coaching and etiquette.

We all know we shouldn’t yell at blind people, but many people do not know what to say or how to behave when they meet someone with a disability. It is not uncommon for people to be apprehensive when meeting people with various physical disabilities. The important thing to remember is that despite the use of a wheelchair, canes or crutches, or the loss of a limb the individual is just like you.

Many people with disabilities have college degrees, are working professionals, have families and share other life similarities. Although each individual story is different, many of their dreams and goals are the same. One major goal that we all have in common is to be treated with respect.

Each person is different. There are some who will find working with people with disabilities easy and others who may be uncomfortable. We have compiled some basic information about working with people with disabilities that may help ease individuals’ concerns…

Peter Ajemian: I’m Not Learning Fast Enough!

Peter Ajemian of Soja Mind/Body:

PeterPortraitBlackWhiteBlackBackgroundReduced

A few days ago I had a conversation with my students in my White Crane martial arts group here at the Soja studio and I feel like sharing their questions and my responses with you so that I can assist more than just my group here.  The initial question was….Given the multitude of challenges of a traditional martial arts practice or refined movement system (like classical ballet, or even your golf game) how long does it take to get good, or feel like you’re progressing significantly?  My response is this: I believe that there is something of a false truth that adult students tell themselves about the need to train extensively for years on end in order to have the themselves feel as though they are ‘mastering’ a move or set of moves.

One obstacle to their feeling they had a good grasp of specific movements or techniques was frustration at not spending enough time at their practice because of the normal adult work and family responsibilities.

My response to that perceived obstacle is that that is a normal predicament and frustration that I hear a lot from my students. They felt like that if they don’t show up to class at least once a day, that they are doomed to mediocrity and/or a lack of understanding of the true essence of any particular technique. I disagree.

Here’s why: I believe that after people have achieved a reasonable foundation of proper body awareness and reasonable body core strength, that they are able to learn new techniques relatively quickly.   I believe strongly in the normal adult human’s capacity to learn continuously throughout their life. Mastering a technique should take a few months at most…and then you should move on to a different technique or a variation thereof. The concept that you need to practice a technique for years on end every day for hours on end in order to have the proper understanding is something of a fallacy in my mind. Surely, if you practice / work on your technique each day… your understanding will come sooner and it will be deeper. I practiced on and off for hours on end almost daily for 30+ years.  During that process I put a lot of activities on the side and managed to inflame my hip sockets so much that I needed to get hip replacements on both sides about 3 years ago. Do you need to spend that amount of time to really get the essence of the movement / technique?   Not really. In fact…for most people I think it would be a waste of time to continue focusing on the same technique within the same context, without focusing their efforts on new varieties of the same or other movements.

For adult new practitioners of any physical activity, be it martial arts, dance, a sport, circuit training, weight lifting, yoga, I believe you would find you were moving along fast enough if you managed to practice 2 – 3 times a week. Of course if you have nothing better to do…no job, no family responsibilities, you could spend a great deal of time practicing each day.   Ohh?  You do have a job?  And you do have a family or a long term committed partnership?   The other side of that question is that if you spend 6 hours training a day to become a master of some new move, what do you lose?  Your time and energy of course!  1) You could easily over train and hurt and exhaust yourself, mostly by not allowing your body to re-cooperate naturally through rest. 2) Now weigh your new found understanding of a particular physical technique with the missed opportunities to interact with your new born children, or your teenagers, or your partner…friends.  As I get older, I feel this second part of the question more and more.

So what do you need to be able to feel you are progressing with your movement practice whatever it is?  It helps a great deal if you have a perceptive, experienced teacher or coach to start out with. Even more important than that I argue it helps if you are very clear about what goals you set for yourself, especially the baby steps, each time you practice.   Mindfulness in setting reasonable, achievable goals for yourself is key here.   

A coach certainly speeds up the learning process.   A critically constructive peer group with a variety of skills and experience is also extremely helpful.   I strive to offer this supportive learning environment each day in my Soja studio…and I’m happy to say that for the most part I feel I achieve this at least to some degree.

I post this conversation in order to inspire YOU to move forward to achieve your short and long term goals, yes, to get you to your class/workout, whatever it is, and not create yet another obstacle to growing your human being.  I would love to hear your feedback and comments from our Soja members and the extended community, teachers and beginning students alike. Your thoughts?

As a personal aside, Soja Mind/Body is local for me. In addition to a good compliment of ongoing hand-to-hand MA (plus yoga) classes for adults and kids, they also host a lot of high quality defensive seminars with people like Rory Miller, Terry Trahan, Violence Dynamics, and Scott Park Phillips—check their Adult Workshops schedule for details if you’re in the SF Bay Area. It’s also my go-to facility for less-lethal and classroom courses. Highly recommended. —Nick

Kathy Jackson: Bad Haircut

For perspective, here are the educational requirements to attain a cosmetics-related license in Washington state.


Education requirements

Minimum required school hours

  • Cosmetologist—1,600 hours
  • Barber—1,000 hours
  • Manicurist—600 hours
  • Esthetician—750 hours
  • Master esthetician—1,200 hours
  • Hair design—1,400 hours

Minimum required apprenticeship program hours

  • Cosmetologist—2,000 hours
  • Barber—1,200 hours
  • Manicurist—800 hours
  • Esthetician—800 hours
  • Master esthetician—1,400 hours
  • Hair design—1,750 hours

Those who want to be instructors in these cosmetic fields must take an additional 500 hours of training and pass both written and practical tests.

***

So what does cosmetology have to do with firearms instruction? What’s my point here?

Well, I’m certainly not suggesting “there ought to be a law!” Self defense is the most basic of all human rights, and that’s a right that belongs to all of us regardless of what we’ve learned or haven’t learned about how to do it effectively.

But I am saying what a shame it is that so many would-be instructors react with horror and disdain when someone suggests that perhaps, maybe, people should independently decide to get more than 17 hours of training before trying teach other people how to handle tools that can kill them.

This is just a little more important than avoiding a bad haircut.

Jim Cirillo on Letting Students Leave Class With Unloaded or Dummy Weapons

Once I had to confront a guy with a machete when I was a rookie cop in the 2-3. I didn’t know I approached him with an empty revolver. What had happened was, we had done indoor training at the armory range. After we fired, the dumbass sergeant made us holster, sent us out, never put us up on the range, and made us reload. I forgot all about it. I walked around for a week with a gun with empty shells in it. Then I got this call, a man with a machete in the basement, and I went in after him. Him and another guy were having words, and this guy said he was gonna cut him with the machete, cut his head off, whatever, and he sees me and I have my totally empty gun and I didn’t know it. I pulled my gun and I says, “Drop it. Drop that or I’m gonna shoot” And he dropped it, and I locked him up. Then, you know when I found out I was unloaded? When I had to go to the outdoor range for the outdoor training and I says, “Holy shit, my gun’s empty, I don’t believe it.” You know, that idiot probably sent eight guys out that day with unloaded guns.

A Bug in fMRI Software Could Invalidate 15 Years of Brain Research

As more and more in training is based on fMRI-based brain studies, this is notable:

Functional MRI (fMRI) is 25 years old, yet surprisingly its most common statistical methods have not been validated using real data. Here, we used resting-state fMRI data from 499 healthy controls to conduct 3 million task group analyses. Using this null data with different experimental designs, we estimate the incidence of significant results. In theory, we should find 5% false positives (for a significance threshold of 5%), but instead we found that the most common software packages for fMRI analysis (SPM, FSL, AFNI) can result in false-positive rates of up to 70%. These results question the validity of some 40,000 fMRI studies and may have a large impact on the interpretation of neuroimaging results. [Emphasis added]

Rory Miller: Teaching Adults

Rory Miller of Chiron Training:

Some of the tenets of adult education versus childhood education are:

  • In order to interest an adult, you must show the adult the value in the lesson
  • You must tie in what you are teaching with what the adults already know
  • You just fit the new information into the world that the adult lives in
  • It is better to use the adult’s current skill and knowledge as a jump board…
