‘….. a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own subjective social reality from their perception of the input.

An individual’s construction of social reality, not the objective input, may dictate their behaviour in the social world.

Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality.

Some cognitive biases are presumably adaptive. Cognitive biases may lead to more effective actions in a given context. Furthermore, cognitive biases enable faster decisions when timeliness is more valuable than accuracy, as illustrated in heuristics.

Other cognitive biases are a “by-product” of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), or simply from a limited capacity for information processing.

A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making incognitive science, social psychology, and behavioural economics.

(Daniel) Kahneman and (Amos) Tversky argue that cognitive biases have efficient practical implications for areas including clinical judgment, entrepreneurship, finance, and management….’

A note about paper sizes.

You need not print these in the same dimensions as they were designed. You can reduce or enlarge them to any size you like.

However, any size smaller than A2 or 16″ X 20″ is difficult to read with ease.

If you want to reduce or enlarge the print size, choose a ratio that is a close match to the size in which the file is designed.

Example: the 24 in X 36 is a ratio of 2:3 width to height. Printing on 18 in X 24 in paper is an ideal alternative.

Where to print

Engineering / Blueprint / CAD printing is the best choice. Print in colour.

Some examples from a basic Google search March 2019.

USA: Staples print online $3.70 for a 24 in X 36 in poster

Canada: Staples print on line $6 for a 24 in X 36 in poster

UK: Plot Giant 4 UK pounds for an A1 sized poster

Ireland: Printco 5.50 Euro for an A1 sized poster

Australia: Officeworks  $7 Aus for an A1 sized poster
