What is Information Overload?
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
“Surviving the collision with tomorrow…”
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
“…there are discoverable limits to the amount of
change that the human organism can absorb”
“…without first determining these limits we may
submit masses of [people] to demands they
simply cannot tolerate.”
Alvin Toffler
(Future Shock, 1970)

Information Overload
Anxiety
Hostility
Senseless Violence
Physical Illness
Depression
Apathy
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
A soldier falls asleep “while a storm of machine gun bullets
splattered around him” not due to physical tiredness, but a
“sense of overpowering apathy”.
Soldiers became hypersensitive and would “hit the dirt” at the
slightest stimuli, increasingly showing anxiety and anger at the
slightest inconvenience.

The overwhelming office?
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
20 million words of new technical
information are recorded each day.
Jackson, W. (2001). Information overload and managerial roles: A naturalistic study of engineers.
At 1000 words/minute, 8 hours/day this is six weeks of reading.

@jdpearce jopearce.co.uk
After reading the information for that one day
you would have fallen behind by 5.5 years!

Cognitive Load Theory
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Defines cognitive load as the total amount of mental
effort being used in the working memory

Describes a universal set of principles for managing
cognitive load that lead to efficient learning.
What is Cognitive Load Theory?
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Total cognitive load is comprised of three types:
Intrinsic Load
Extraneous (Irrelevant) Load
Germane (Relevant) Load
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Imposed by the inherent complexity of the task being performed.
e.g.
Learning to juggle 10 balls is inherently more
complex than learning to juggle 3.
Intrinsic Load
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Imposed by the inherent complexity of the task being performed.
Manage by breaking large tasks into smaller ones!

@jdpearce jopearce.co.uk
Imposed by distractions or tasks which are irrelevant to the goal.
Coping with a loud environment
Unfamiliarity with a development tool
Unreadable code
e.g.
Extraneous (Irrelevant) Load
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Try working somewhere quieter…
…or wearing headphones?
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Reduce the number of tools or libraries to a minimum…

Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Imposed by distractions or tasks which are irrelevant to the goal.
Manage by reducing the number of irrelevant distractions and tasks!
Extraneous (Irrelevant) Load
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Load imposed by tasks which are relevant to an overall goal.
Repetition and context variation give us the skills to
apply knowledge in a wider variety of situations.
Germane (Relevant) Load
Helps us to connect bits of information and form more
complex schemas
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Repetition = Practice
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Context Variation
Tree?
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
Load imposed by tasks which are relevant to an overall goal.
e.g. If the goal is to promote better understanding of a codebase
Vary the areas of the codebase a developer works in
Pair junior developers with those more experienced to
gain varied perspectives and skills
Germane (Relevant) Load
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
We constantly need to learn…
Hacking Your Head : Managing Information Overload
@jdpearce jopearce.co.uk
But there are limits on our ability to learn…
