The Dunning-Kruger effect

Published: October 16, 2012 at 2:09pm

A reader sent this in:

The Dunning–Kruger effect is a cognitive bias in which unskilled individuals suffer from illusory superiority, mistakenly rating their ability much higher than average.

Kruger and Dunning proposed that, for a given skill, incompetent people will:

1. tend to overestimate their own level of skill;
2. fail to recognize genuine skill in others;
3. fail to recognize the extremity of their inadequacy;
4. recognize and acknowledge their own previous lack of skill, if they are exposed to training for that skill

Across four studies, the authors found that participants scoring in the bottom quartile on tests of humour, grammar, and logic grossly overestimated their test performance and ability. Although test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.

    On another note: 10 years’ jail for raping 3 daughters (The Times – October 16, 2012

    “In jailing the man for 10 years, Mr Justice Michael Mallia took into consideration the plea bargain that was reached between defence lawyers Anġlu Farrugia and Michael Sciriha and the Attorney General’s Office.”

    What sort of plea bargain can justify three and a half years jail for each innocent life ruined forever.

    I hope this man will drop his soap a hundred thousand times in the showers. Perhaps he will experience slightly what his daughters were forced to go through.

      The sDunning Diane Kruger.

      Do forgive me.

      Right, wrong Kruger, but loved when I met her in Peppino’s with Brad.

      • H.P. Baxxter says:

        A thousand ships wouldn’t be enough for her. Mind you, she’s a shyte actress, but we’re not exactly after her acting skills, are we?

        So tell me, Harry, do you often hobnob with the jet set? Any DSK parties I can attend?

        Cheers.

        Whenever you can extricate yourself from your over so busy schedule, I will certainly accommodate. Have already contacted DSK, a fresh nymph is awaiting.

    Franco will assume you’re referring to Austin Gatt, Cassar, Claudette Buttigieg, etc.

    It’s another test which will see Franco scoring 100 in.

    Oh what an eye-opener for those who should know better.

    Franco Debono from ‘A’ to ‘Z’

    His world revolves around Form IIc report card. The world of a 14 year old and not matured since..

  8. Stanley J A Clews says:

    Franco Debono I presume?

  9. anthony says:

    What about those people who estimate themselves to be in the 99th percentile?

  10. rowena smith says:

    It seems john dalli just resigned from his post as EU Commissioner.

  11. kev says:

    Quick, Gonz. Komissar Dalli is being forced to resign. Dispatch Franco instead. He’ll love it and so will Barroso.

  12. allamana says:

    This shows that the more incompetent one is, the more noise he/she makes.

    Ergo

    Franco, who is the noisiest of all politicians, is a cuc inkarnat bic- certifikat.

    In simpler English: “The whole problem with the world is that fools and fanatics are always so certain of themselves but wiser people are full of doubts (Bertrand Russell)

  15. JPS says:

    Fantastic – bang on! They should now take Franco as living proof and they stand a chance of winning the Nobel prize for research!
