Just Finished Reading: Battle Hymn of the Tiger Mother #books

leave a comment »

I started begging my mother for piano lessons from a very young age, had my mother been a Tiger Mother I would have been a child prodigy. I’d seen Amy Chua in an interview program and had wanted to read Battle Hymn of the Tiger Mother as an instruction manual to raise my child as a music virtuoso. And although the book is not a step-by-step guide to becoming a Tiger Mother I am glad I read it.

The book is an autobiographical view of the way Amy Chua raised her daughters Sophia and Louisa (Lulu) to become straight A students, and focusses mainly on her teaching her children to play the musical instruments of her choice. In the end it devolves into a war of attrition between Amy and Lulu, resulting in a revelation for the Tiger Mother.

Peer assessment and the Dunning-Kruger effect #hr #management

leave a comment »

What about it?

Whilst having discussions on a ‘thinkers’ board that I infrequently-frequently visit, someone mentioned the Dunning-Kruger effect in relation to specific politicians.

So I looked it up and something started to dawn on me.

Of late I have seen quite a number of companies adapting the ‘Google method’ of peer assessment when it comes to hiring new personnel, but for some reason those companies were having rather a decline in technical competence instead of getting the increased benefit of adding more ‘brainpower’.

As I understand it, and as related to my own observations in the peer assessments, the problem lies here in points 2 and 3 of the hypothesis put forth by Kruger and Dunning:

2) Fail to recognize genuine skill in others;

Oftentimes the higher skilled candidate is being dismissed because “he talks about weird things and can’t communicate properly” or variations thereof.

Now what I have seen Human Resources do is not recognizing this problem but rather projecting a form of ‘insecurity’ on the assessing employee ‘He may be afraid of his position’, whereupon they start complementing and ‘securing’ the assessing employee. It would go too far too add Pavlovian conditioning to this story, but it may not be too far from it.

3) Fail to recognize the extremity of their inadequacy;

Dunning has drawn an analogy to someone having an impairment, but I think a much clearer and less insulting explanation can be given by the concepts of Flatland (when read without the Victorian context, that is).

What does that mean for the business?

As for the origin of the inadeqacies, I leave that for the respective physicians and psychologists, but there are a few common mistakes companies make that help in attenuating this effect within their ranks.

- The HR departments are not sitting at the table when the peer assessments take place

This has the effect of ‘ganging up’ on a potential candidate; remember that the assessing employees will subconsciously defend their comfort zone, so no fresh blood that dares to challenge even the group of ‘old hands’ will ever be given a good mark.

And in technology, zealotism is stronger than in religion. Mention the wrong editor somewhere and you are classed ‘unqualified’. Mention that you do not have a fascist adherence to Linux/MacOS/Windows/Anythingatall and you are classed ‘incompetent’.

The way to remedy this is to have a properly prepared (as in read up, albeit cursorily, on the subject matter) HR staff sit at the table and support the candidate in matters of confidence and to ‘call off the hounds’ when needed. Also, the HR staff should ask questions like ‘why is this editor thing important in our company?’ so as to prevent the technology policies becoming the pre-conditions for a personal playground of the techs.

- Sitting personnel has gotten to the position on merits of ‘employment years’ and ‘being there first’ or ‘helping to set it up’

Often, because ‘in the land of the blind, one-eye is king’, a manager or ‘chief’ of a technical department is someone that has been a long time in a company. This is a tradition that stems from the old ‘Foreman’ habit; a senior gets to lead his peers because he knows very well what the work entails and he knows the peers very well.

But in ICT, I really have to say this, a lot of technically competent people have problems when interacting with the rest of the world. I will even go so far as to say that some of these people are in ICT because of their Rainman-like qualities; they simply are prone to defend against anything that threatens the world they have created in their own mind.

This can be remedied by not giving them decision powers. They should have all the execution powers, or put differently; they should be allowed to decide on ‘how’ to do things, but never ‘what’ to do.

Here then comes a gray area; it is sometimes hard to see when it is a ‘how’ and when it is a ‘what’. But there’s a good rule of thumb for it (this is just a marker, not a hard fact): if it involves anyone outside of the inhouse technical crew, treat it as a ‘what’. All activities done by that technical crew can be treated as ‘how’.

Obviously it never is going to be that simple, but think of this as having a race-horse pulling a gurney; the horse pretty well knows how to run by itself and given practice it even knows how to turn etc. But because the jockey has more information (i.e. the strategy, the strength and endurance of the competition) and has the ability to make judgements on that information (i.e. if the others are conserving energy, if the other horses are at their peak, when to fully go all-out) it must always be the jockey who is in control.

The horse can do things the jockey can not, but the jockey can do things the horse can not. And if the horse decides that it knows the course better than the jockey, the race will be lost most of the time.

The horse does not see it’s inadequacy in decision making, because it can outrun that little jockey even on a bad day…

And now what?

Well, just because they know more about technology and about the work they do, that does not mean they know more about healthy and proper assessment procedures.

When assessing new personnel, have the tech department set up a kind of exam with a scoring method. That way they can ask anything they want and open questions can be scored ‘double blind’ if wanted (although simply anonymous is usually good enough).

This test can then be sent to an outside consultant or other tech company to verify both the validity of questions and the standard answers.

You can have candidates (give them fair warning though that you are going to do this) take this test and have it objectively scored. This makes for an up-to-date questioning and it also gives the candidate the possibility to defend his/her answers against the scoring because it can be done fully in writing. Sometimes that will yield that the candidate is overqualified for a certain setting. But that leaves the candidates dignity in place and gives the tech department a chance to work on themselves.

The HR staff can assess the social qualities and all other properties after a candidate has gotten through the test.

I sometimes hear that ‘it is hard getting good personnel’, but I do not think so. I think it is hard breaking down the little kingdoms that have come to be and that in an open and social world, there really should be no place for them anymore.

Just Finished Watching: Tripping The Rift #series

leave a comment »

A good friend of mine told me about Tripping the Rift, and highly recommended it. Word of Mouth is not the way I usually get my recommendations, although I get many recommendations that way. Most times somebody will give me something based on their experience, or will pass it on to me after they have done reading or watching it.

Tripping the Rift is an adult cartoon, with a story line similar to Firefly. A band of space privateer/smugglers who constantly get into trouble with the leaders of the “good” Confederation and “evil” Dark Clown Empire. Chode – a horny purple alien – causes most of the trouble, which ends up being resolved by him and his misfit crew: teenage lizard, sex android, gay robot, and an ugly cow/hippocentaur. Nothing is sacred, which makes it all the funnier.

It is fun light viewing, and definitely not suitable for children. It probably won’t make you smarter.

It’s the incentive structure, people! Why science reform must come from the granting agencies.

Reblogged from The File Drawer:

Another day, another New York Times report on bad practice in biomedical science. The growing problems with scientific research are by now well known: Many results in the top journals are cherry picked, methodological weaknesses and other important caveats are often swept under the rug, and a large fraction of findings cannot be replicated. In some rare cases, there is even outright fraud.

Read more… 827 more words

I discussed this same issue in Medicine sometime ago, if it were so that a solution is thought te have been found them the sampling rate should increase. This is a case of search satisfaction – you expected to find something found something so you stop searching rather than finishing your search. While in a larger sample set or more regression to the mean takes place, which means the results come closer to the average..

Just Finished Reading: The House of Silk #sherlock #holmes #books

leave a comment »

Like Anthony Horowitz I’ve always liked Sherlock Holmes, perhaps it is because my mother joked that I was related to the sleuth. Or because I visited 221B Baker Street as a child. In any case I am much enamored with the genius of Sir Arthur Conan Doyle, and as have been disappointed with many other tributes to the creator. And I was shocked whet James Randi revealed in his book that Doyle was a firm believer in the fairies of Cottingley Glen.

The House of Silk is an enthralling book, filled with the subterfuge which can be expected from a Holmes tale. It combines two overlapping stories and can be placed in the middle of the canonical Holmes series. It touches on subjects which, although they would not be out of place in Victorian Britain, might not be expected in a Holmes story. Standing on its own the novel is good, and seems well researched. As an amateur nitpicker I would have loved to find a inconsistency or glaring error, and didn’t. :)

It certainly can be called a good Holmes novel.

What is wrong with ICT?

leave a comment »

A day ago I read PHP: A fractal of bad design, and it made me sit down and think about writing this entry, of which the kernel has been gestating for quite a long time.

I see this a lot; pro’s ranting about an aspect of our ‘craft’ that has gone totally pear-shaped; programmers complaining about the languages or the quality of code they are asked to fix and/or maintain, systems administrators that just can not believe the insanity that is brought down on them because of either laziness of the in-house personnel or management-made bylaws.

Cryptographic specialists (even mildly spoken ones like Bruce Schneier), hackers nee security specialists, software designers… the whole palette of people that actually are proficient in their work gripe and complain.

Just Finished Reading: Flim-Flam! #books

leave a comment »

Recently I got into a discussion about astrology and was told that it was obvious that I’d never had a good astrological reading. I have difficulty dealing with people who choose to believe in pseudoscience, and have much in common with James Randi in this respect. Where he and I diverge is in our treatment of these fanatics, I tend to avoid them like the plague. The same holds for the people who suffer from paraskevidekatriaphobia, the belief in the power of Friday the thirteenth.

Isaac Asimov writes in his introduction to the book that “[u]nder these circumstances, what crime is greater than that of deliberately misteaching the public about science, of deliberately misleading them, of defrauding them, of feeding and stimulating their ignorance?” Randi goes on to savagely ravage all the purveyors of trickery explaining that he seeks “to prove that ‘psychics’ use trickery by duplicating their wonders by trickery.” I believe that the main issue with this book is not that it is not written with the mainstream in mind, it is that the main stream media is more interested in spouting ridicules fiction and trickery rather than the truth, and the public eats it up. This is probably why politicians do so well.

I’m sure you had a nice day. And if you didn’t read Flim-Flam!

Red Hat Open Cloud Tour #RHCTams #conference [UPDATED]

leave a comment »

Today I spend my day at the Red Hat Open Cloud Tour, this is what happened today:

Just heard the opening by Rajiv Sodhi, who is here despite having a baby due any moment.

Margaret J. Rimmler’s keynote was interesting. One of the key takeaways being openness RedHat customers should have the choice to remain portable and replace RedHat, if that is what they want. Read the rest of this entry »

Proof of Concept: Shopper App

leave a comment »

I often get people ask me to develop phone applications based on an idea and with little other input besides the idea itself. I usually ask them to write me a proposal and send that to me, knowing that most people will procrastinate – as it turns a fun idea into work – I rarely hear anything back. Not so in this case, a friend brainstormed a shopping application and we made the following rough mock ups using OmniGraffle.

GOTO Amsterdam 2012 organizer Trifork violating @Eventbrite TOS #fraud [UPDATED]

leave a comment »

I believe that violations of terms of services can occur for many different reasons, usually this comes from not reading them. I am the first to complain about unfair terms, or the faulty application of terms to non-violators. Some violations are so blatant that they should be mentioned. And that’s where this tale starts:
