“The idea that things are either true or false should possibly take a rest …. I wonder, and this is just a modest proposal, if scientific truth should be identified in a way that acknowledges that it's something we know and understand for now – and in a certain way.” - Alan Alda

BALONEY DETECTION KIT

Slide 30

Slide 30 text

Baloney Detection Kit • Wherever possible there must be independent confirmation of the facts. • Encourage substantive debate on the evidence by knowledgeable proponents of all points of view. • Arguments from authority carry little weight. • Spin more than one hypothesis • Try not to get overly attached to a hypothesis just because it's yours. • Quantify, wherever possible. • If there is a chain of argument every link in the chain must work. • Occam's razor - if there are two hypotheses that explain the data equally well choose the simpler. • Ask whether the hypothesis can, at least in principle, be falsified. In other words, it is testable? Can others duplicate the experiment and get the same result?

Slide 31

Logical Fallacies • Ad hominem • Argument from "authority" • Argument from adverse consequences • Appeal to ignorance • Special pleading • Begging the question. • Observational selection. • Statistics of small numbers. • Misunderstanding the nature of statistics • Inconsistency • Non sequitur • Post hoc, ergo propter hoc • Meaningless question • Excluded middle • Short-term v. long-term • Slippery slope • Confusion of correlation and causation • Caricaturing (or stereotyping) a position to make it easier to attack. • Suppressed evidence or half-truths. • Weasel words

WARNING: Playing in the role of In-Person Baloney Detection Kit at a party or online doesn’t make you a popular nor does it make you a person that people want to actually listen to or be around. Use judgement and “social tact” at all times.

“Try not to get overly attached to a hypothesis just because it's yours. It's only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don't, others will.” - Carl Sagan’s Baloney Detection Kit from “The Demon Haunted World”

McNamara’s Fallacy

Slide 46

Slide 46 text

The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide. — Daniel Yankelovich "Corporate Priorities: A continuing study of the new demands on business." (1972)

I am of the opinion that parallax is a waste of time and resources in order to achieve an effect that users are already immune to and has terrible scrolling performance in a multi-device world.
