The Dunning-Kruger Effect

November 15th, 2008 by Moti Karmona | מוטי קרמונה · 5 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 | מוטי קרמונה · 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:

  • I have removed the sitemeter performance penalty widget
  • I have installed the WordPress Super Cache Plug-in which wasn’t that simple with my webhost4life hosting limitations.
  • I have removed couple of images and reduce the blog top image size from 80k to 5k (!!!)

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!
