Expectations ~ Another problem with observation is that our expectations can influence what we see, hear, or believe…. What if everything we hear in the news is really a lie or misinformation of the truth… http://m.youtube.com/watch?v=1zqOYBabXmA
2
Icebreaker: In your journal please respond to the following questions: Is science the only road to knowledge? Does science have a monopoly on truth? How far do the natural sciences give us certainty?
3
Natural Sciences include: Physics Chemistry Biology
4
Some argue that science is the only road to knowledge Natural Sciences are the dominant cognitive paradigm (model of knowledge) Science is not God and has weaknesses and limitations Scientific beliefs change over time.
5
How have advertisers used the language of science to market products?
7
Inductivism is the traditional picture of the scientific method: Observation Hypothesis Experiment Law Theory
8
Relevance – you must begin with what is relevant and irrelevant to the problem. Expectations – expectations can influence what we see Expert Seeing – use of scientific equipment can often further complicate things The Observer Effect – the act can affect the outcome.
9
Relevance – it is always possible to overlook a factor Expectations – overconfidence Expert Seeing – observer is only as good as their equipment. The Observer Effect – the observer changes the experiment – thermometer in the hot tea.
10
Confirmation Bias – people look for evidence that confirms and ignore what goes against them. A good scientist is aware of confirmation bias.
11
Karl Popper (1902-1994) – tried to distinguish science from pseudoscience (Marxism/psychoanalysis). “A theory that explains everything explains nothing” – a scientific theory must put itself at risk to be disproven.
12
Paradigm – an overarching theory shared by a community of scientists, such as physicists, chemists, or biologists, which is used to make sense of some aspect of reality. i.e. – Newtonian mechanics in physics, Atomic theory in chemistry, & Evolutionary theory in biology.
13
Science has been responsible for a large body of knowledge in the past 300 years. Science is limited to our understanding of our world around us. Paradigm shifts occur with new knowledge.

C - Claim: Make sure you clearly understand what is being proposed. R - Role of the claimant: Who is making the claim and is there something in it for them? What biases can you identify? I - Information backing the claim? What evidence is offered in support of the claim. Is it anecdotal or objective/verifiable? T - Test: How might we design an adequate test to verify the claim? I - Independent Testing: Has any unbiased source carried out an independent test of the claim? Are the results published in a reliable journal? C - Causality - What is held out of the explanation of the claim and is it consistent with the physical laws of the universe?
