4.2 Bounded rationality and the use of heuristics

As decision makers, none of us has infinite resources or time to devote to gathering and analysing information. In addition, we all have significant limitations to the amount of complexity we can cope with. Thus, even where we make conscious efforts to make decisions according to a formally rational process, we often need to make simplifying assumptions and accept limits on the availability of information and the thoroughness of our analysis.

As noted above, we constantly use heuristics

9.4 Summary of Section 9

This section has illustrated what has to be done, by way of a long-term study, to yield meaningful information on the relationship between genes and development and the behaviour of the organism. It also illustrates the hugely complex nature of the relationship between genes and development and the behaviour of the organism. Yet this complexity is not the exception, it is the rule.

Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.

Fe, C 1.0 (wt%), hypereutectoid alloy
This secondary electron SEM image shows the cementite delineating prior austenite grain boundaries with a thin layer. The amount of proeutectoid phase is very low, with the majority of the area being taken by the pearlite eutectoid. Again each pearlite cell has a different orientation with the ferrite phase being selectively etched.
