Question of the week Monday, Nov 28



I have adapted this is from the Univ of Manitoba in Canada, but is basically the BDK!!!

The following are some guidelines for critical thinking. (BDK)

          1. Ask questions; be willing to wonder.          
2. Define the problem.                                  
3. Examine the evidence.                             
4. Analyze assumptions and biases.               
      5. Avoid emotional reasoning.
      6. Don’t use either/or thinking or over generalize.
      7. Consider other interpretations.
      8. Tolerate uncertainty.

Each of the statements below violates at least one of the guidelines for critical thinking. 
Identify the guideline that was violated and give a brief explanation for your choice. Each is worth ONE POINT.

 

    1.     I get disgusted with my science classes. We study the “principle of this” and the “theory of that.” Aren't there any laws? Why can’t scientists make up their minds and stop acting like they don’t know anything for sure?



    2.     Since we have never been visited by extraterrestrials, and have had no communication from outer space, we can safely assume that intelligent life exists only on our own planet.

    3.     I looked at several issues of the Journal of Parapsychology, a periodical that publishes research on psychic phenomena. Every article confirmed the existence of ESP, so I don’t understand why most psychologists are skeptical about it.

    4.     Jezebel bought a bottle of pain reliever because a TV commercial claimed that most hospitals prescribe it.

    5.     You’re either for us or against us.

  1. 1. Tolerate uncertainty . I say tolerate uncertainty because she is saying that can't scientist make up their mind which means that they are uncertain and she says she is digusted by her science lessons which means she can't tolerate them

  2. 5. Consider other interpretations. It is this because it is stating that you are either for us meaning you either except what we are saying or you are against us therefore we disagree to hearing what you have to say as it is not the same as what we have to say . So they are not considering other interpretations

  3. 2. Be willing to wonder ask questions. I have chosen this one because he says that since we have never been visited by ET's we can safely assume that there is only intelligence on our planet. He is not asking other questions and he is not willing to wonder that there may be intelligence on other planets.

  4. 4. Examine the evidence. Jezabel bought a pain killer because a tv advert said that hospitals prescribe it. He didn't check if that was true or not he didn't look for evidence that that was the truth the only evidence he went by was the tv advert. He also didn't see if the company was a well reputed company or not or if they are most likely to be lying or not.

  5. 1. Avoid emotional reasoning. The person has determined that science is digusting because it has no certainty however science may not be disgusting. She has used her personal opinion.

  6. 3. Define the problem. He has said that he has confirmed from other articles that ESP exists and does not understand why other scientists are skeptical but he has not defined the problem to us.

    to me
    1. is number 5 avoid emotional reasoning, but has violated it by having the persons own opion and annouance about science
    2. is number 7 we may not have evidence but some people see that there is but are still waiting for a sign
    3. is 6 and 7 veryone has there own opion and this person keeps thinking about.
    4. is number 4 as she has gone out just because of a comercial without loooking at the details
    5. number 6 as it is a big statement and the problem is not defined.

    5. "You're either for us or against us" - this violates the fact that one can view a conflict from a neutral angle - grey is a colour just like black and white.

  11. 2. "Intelligent life exists only on our planet" - One cannot assume that although one has no evidence for the existence of extraterrestrials, that this may not be found in the future. Also, the BDK states that one should not only have negative evidence against an opposing claim, but positive evidence for one's own claim. This writer has not given an evidence as to why one should be sure that extraterrestrials will not be discovered in the future.

  13. 3)Perhaps the journal publishes only studies that support the existence of psychic phenomena

  14. 1-The student seems more interested in answers than in “truth.”

  15. 2) Since you cannot prove a negative, you must also consider other interpretations (7) for the absence of contact with other planets.

  16. 1) Tolerate uncertainty.
    3)Examine the evidence

    to me
    1. examine evidence because he is still learning the topic and he hasnt research the laws. also tolarate uncertainty as hythosis often have to be tested and compered multiple times before a statement is concluded.
    3. he should compare others work to the book and compae different evidence and be aware of different opions
