“With respect to learning by failure, it’s all fun and 
games until someone gets a larval cyst in the brain.”
Everything should be made as simple 
as possible, but not simpler.
“There is a problem in discussing 
systems only with words. Words and 
sentences must, by necessity, come only 
one at a time in linear, logical order. 
Systems happen all at once. They are 
connected not just in one direction, but 
in many directions simultaneously.”
The design and management 
of information systems. 
Understanding the nature 
of information in systems.

Categories are the cornerstones of cognition and culture.

“The system always kicks back.”
“How can I know what I 
think until I see what I say?”
Culture
National values are fixed. Organizational practices are not.
Double-loop learning in organizations (and individuals) is rare.
The relationship between information and culture.
“There’s a secret about MRIs and 
back pain: the most common 
problems physicians see on MRI and 
attribute to back pain – herniated, 
ruptured, and bulging discs – are 
seen almost as commonly on MRIs of 
healthy people without back pain.”
“If you want to accelerate 
someone’s death, give him a 
personal doctor. I don’t mean 
provide him with a bad doctor. 
Just pay for him to choose his 
own. Any doctor will do.”
Limits
“It is now my suggestion that many 
people may not want information, and 
that they will avoid using a system 
precisely because it gives them 
information…If you have information, 
you must first read it. You must then try 
to understand it. Understanding the 
information may show that your work 
was wrong, or may show that your work 
was needless. Thus not having and not 
using information can lead to less trouble 
and pain than having and using it.” 
Calvin Mooers (1959)

“We shape our buildings. Thereafter, they shape us.” – Winston Churchill
“Tell me about a day in your life.”
“Willpower is the single most 
important keystone habit for 
individual success.”
“A culture of generosity.”

“Where architects use forms and spaces to design 
environments for inhabitation, information architects use 
nodes and links to create environments for understanding.” 
Jorge Arango, Architectures (2011)
“When we try to pick out anything by itself, we find it 
hitched to everything else in the universe.” 
John Muir
