The Dunning-Kruger Effect

November 15th, 2008 by Moti Karmona · 3 Comments

The Dunning-Kruger effect is a cognitive bias in which people who are worst at a task show the most illusory superiority, rating their own ability as above average (e.g. shut up I hack you :)

Justin Kruger & David Dunning have tested and verified the following predictions:

  • Incompetent individuals tend to overestimate their own ability and performance 
  • Incompetent individuals fail to recognize genuine skill in others (it takes one to know one ;)
  • Incompetent individuals fail to recognize the extremity of their inadequacy (“One puzzling aspect of our results is how the incompetent fail, through life experience, to learn that they are unskilled”)
  • If they can be trained to substantially improve their own skill level, these individuals can recognize and acknowledge their own previous lack of skill (There is still some hope)

Do you have the confidence that this post isn’t about you? 

Think again… (!!!) - “ignorance more frequently begets confidence than does knowledge” (Charles Darwin)

Do you think this post is about you?

Might be considered vain but interesting enough, the same research have shown that the top performers tended to underestimate their own performance compared to their peers (see chart below). 

So… if you find this post boring, obscure, stupid, annoying, poorly written or inappropriate than please keep in mind it isn’t something I have committed knowingly.

Wasting Time on Blog Performance

November 2nd, 2008 by Moti Karmona · 2 Comments

Last weekend I was wasting time on my Blog performance and all I got is 10 sec. and this lousy post.

Quick profiling with FireBug and YSlow FireFox extensions have done great wonders with my amazingly slow, not-really-that-interesting, hosted (webhost4life) WordPress blog.

Main action items:

Results:

  • Main blog page returns after ~1 sec.
  • I am still getting a lousy grade with the YSlow tests (62) but it seems like the YSlow blog post announcement have failed too… (57 :)
  • Post pages are still slow (~2-4 sec.) but I know what I have to do the next time more than 1 million readers will complain…

Have fun!

Technorati’s State of the Blogosphere / 2008

September 22nd, 2008 by Moti Karmona · No Comments

Thing I & Thing IITechnorati have finally started to release the “state of the blogosphere” report.

I must admit I was really waiting for this shitty report and I hate the fact that I need to see this reports in shards (will be released in five consecutive daily segments) but it was worth waiting until now.

2008 Blogosphere statistics includes:

  • 133 million blogs (indexed by Technorati since 2002) was 70 million last year… (The State of the Live Web, April 2007)
  • 7.4 million blogs posted in the last 120 days
  • 1.5 million blogs posted in the last 7 days (did you? ;-)
  • 900,000 Blog posts in 24 hours = ~10 Blog posts per sec. (!!!) – Technorati claims that spam filtering have reduced the numbers they published last year (1.4 million blog posts per day)
  • 66% of bloggers are male…
  • 63% are ages 25 to 44
  • 79% personal blogs
  • 59% have been blogging for more than two years.
  • 44% are parents
  • … and with the mean annual revenue of $6K blogs are also claimed to be profitable (a.k.a. not mine)

WOW (!!!)

Levan Polkka

March 28th, 2008 by Moti Karmona · No Comments

Nuapurista kuulu se polokan tahti
jalakani pohjii kutkutti.
Ievan äiti se tyttöösä vahti
vaan kyllähän Ieva sen jutkutti,
sillä ei meitä silloin kiellot haittaa
kun myö tanssimme laiasta laitaan.
Salivili hipput tupput täppyt
äppyt tipput hilijalleen.

Ievan suu oli vehnäsellä
ko immeiset onnee toevotti.
Peä oli märkänä jokaisella
ja viulu se vinku ja voevotti.
Ei tätä poikoo märkyys haittaa
sillon ko laskoo laiasta laitaan.
Salivili hipput.

Ievan äiti se kammarissa
virsiä veisata huijjuutti,
kun tämä poika naapurissa
ämmän tyttöä nuijjuutti.
Eikä tätä poikoo ämmät haittaa
sillon ko laskoo laiasta laitaan.
Salivili.

Siellä oli lystiä soiton jäläkeen
sain minä kerran sytkyyttee.
Kottiin ko mäntii ni ämmä se riitelj
ja Ieva jo alako nyyhkyytteek.
Minä sanon Ievalle mitäpä se haittaa
laskemma vielähi laiasta laitaa.
Salivili.

Muorille sanon jotta tukkee suusi
en ruppee sun terveyttäs takkoomaa.
Terveenä peäset ku korjoot luusi
ja määt siitä murjuus makkoomaa.
Ei tätä poikoo hellyys haittaa
ko akkoja huhkii laiasta laitaan.
Salivili.

Sen minä sanon jotta purra pittää
ei mua niin voan nielasta.
Suat männä ite vaikka lännestä ittään
vaan minä en luovu Ievasta,
sillä ei tätä poikoo kainous haittaa
sillon ko tanssii laiasta laitaan.
Salivili.

I have nothing to add…
