Mlodinow has book Elastic thinking, which sounds interesting and where he mentions bottom up processes/thinking; which he equates with elastic thinking.

I have watched numerous videos about it, and even read some sample chapters of the book - but to my surprise, it is still unclear to me what exactly he means by bottom up thinking?

One unclear quote from the book is:

Elastic thought is where your new ideas come from. Imaginative, original, and non-linear, it is “bottom-up” thinking, in which insights percolate into the mind, seemingly from nowhere.

Another unclear quote:

Elastic thinking is about stretching your mind and using ‘bottom up’ processing in the brain rather than the top down executive functions that drive analytical thinking

Can someone please bring some simple and concrete examples from daily life, of what is bottom up thinking?

ps. His book is based on research and says it is known term in science community, this elastic thinking/bottom up thinking, and hence my hope people here may know what is it.

Hutchinson, B. (2002), an article in the book Synergy Matters by Adrian M. Castell may help in understanding what is meant by bottom up thinking and the opposite, top down thinking.

[T]he term ‘top down’ is used to describe an approach to problem solving where the problem space is defined first. The worldviews of the participants are used to conceptualise the desired state of the proposed system. Once this is achieved, the system is developed within this boundary. The components, or subsystems are derived within the context of the predefined desired state. The term ‘bottom up’ is used to describe an approach where no assumptions are made about the boundary of the problem space. The behaviour of component parts are rationally observed to determine the properties they have. Management decisions, or system designs are then based on the observed behaviour of components.

An example given in the conclusions is:

[I]nvestigating a system failure in bottom up mode would look for causes at the element level, or more precisely, at their interactions. The top down mode would tend to look at the overall system, and would put ‘blame’ on the system itself and how it functions, rather than emergent properties of system element interactions.

Think of it like a brick building. You need to build it from the bottom up, with each brick being correctly placed to form the correct shape etc. If the bricks are placed differently, you may get a different building, or maybe you will get the same building but badly constructed.

Take the following as a more detailed example comparison...

There is a team of researchers working on a task and each member inputs their findings into a computer system which analyses the results and comes up with a conclusion.

The program relies on accurate information from each team member entry but there was a slight error in a couple of entries producing an incorrect conclusion by the system.

A top down thinker would blame the computer system analysing the results. A bottom up thinker would analyse what the system was analysing and how, leading to them finding the real cause.

    $\begingroup$ better than my quotes, but still bit vague; more (concrete) examples would be welcome. $\endgroup$ – user21349 Jan 21 at 7:06
  • $\begingroup$ just a note: mladinows book is on research in psychology, whereas your link on research in management science. Not saying they aren't related, just made a note. $\endgroup$ – user21358 Jan 21 at 17:59
