Size of Boeing hangar. 40.000 tons. 4.000 Gwatt

YOUR BRAIN: 80 trillion connections ( = x 2000)
connected with 50-100 trillion of body cells
= 150 trillion connections to connect everything
(= x 4000) ... and IT WORKS

Very high risk of being irrational,misled by emotions, cognitive biases, heuristics, instincts…
For less stupid errors, for more creativity: reflect (or drill).

Reflective Brain Reflex Brain
•Unconscious
•Ad hoc: sensory now is all
•Parallel: many things at the same time
•Extremely fast non-rational shortcuts
•No need for conscious attention
... attention is drawn•Needs very little brain-energy
•Selfish: survival + procreation
•Shared with all animals with a brain
•Very old in evolution
•Conscious
•Can disconnect form reality
•Sequential: one thing at a time
•Slow, logical, rational
•Needs concentration,
... paying attention
•Gulps energy
•Can be wise, ethical, creative
•Uniquely human
•Very recent in evolution

Do you want a car mechanic
doing a brake job on you car
while he is multitasking?
When you think you can do your job well while multitasking
You are WRONG and you know it!
MULTITASKING IS VERY IGNORANT
You know multitasking is not a good idea !!or… is your job less difficult, less important?
Do you want a surgeon
operating on you
while she is multitasking?

Every beep or pop-up = 2 minutes of concentration lost !

PARALLEL MULTITASKING : time lost + information lost
Problem #1: you are continuously SWITCHING
Loss of energy, memory, reflection, understanding etc…
Remember:
And it’s even much worse than that !!!

PARALLEL MULTITASKING : loss of information and time
Problem #2: Partial attention = ILLUSION !!
Your reflecting brain can only pay attention to ONE “channel” at a time
Total loss
The reality of what you do: FRACTURED attention
Total loss Total loss
Total loss Total loss Total loss
While you do emails you do NOT hear what is being said!
People who think they hear it when it’s important are WRONG !!
They are deceiving themselves, and their brain helps because…
It’s even worse than that !!!

PARALLEL MULTITASKING : time lost + information lost
If you think you hear/see it when it’s important you are WRONG !!
Your brain hates the gaps and fills them in guessing what’s lost!
GUESS GUESS GUESS
GUESS GUESS GUESS
Problem: while simultaneous/parallel multitasking ex. in meeting
YOU DO NOT HEAR WHAT’S SAID
YOU HEAR THINGS THAT ARE NOT SAID
Problem #3: your brain fills the gaps guessing !
Efficient ???
Until today: Ignorant. After today: STUPID !

BABY DEAD IN CAR
Baby died, forgotten in a car
on a hot parking
1. BEING ALWAYS ON/ALWAYS CONNECTED
your body is in one place, your mind in another
and your mind is in reactive mode
2. MULTITASKING: especially if you combine tasks from totally
different domains like work and home.
Never forget: Our conscious brain cannot multitask
3. NEGATIVE STRESS: too much stress and/or too long stress.
Negative stress makes clever people behave stupidly
4. LACK OF SLEEP undermines memory and other intellectual
functions
Only one is enough to significantly increase the risk of
making very big, stupid, mistakes yourself!
How is this possible ??
This would never happen to me !!!!
You are totally wrong!!!! It can happen to you too, with a combination of:

Because you are not very clever (unlikely)
Because you are struggling with a neurosisNeeding to feel important or show importance, needed; lack of self
confidence, being a pleaser, lack of self respect, not taking responsibility
while blaming others, lack of willpower, etc…
Because you are addicted
After today, you can no longer claim ignorance!

incredible experience using their iPhone in the car,” said Greg Joswiak, Apple’s
vice president of iPhone and iOS Product Marketing. “iPhone users always
want their content at their fingertips and CarPlay lets drivers use their iPhone in
the car with minimized distraction.“

“…but what’s the difference between talking on
phone and talking with passenger…”The difference is very big, except if emotional conversation.
•Passenger is in the same context
•Adapts the content, the pace of the conversation to the traffic
situation, sometimes proactively,
•Traffic part of conversation helping to stay focused
•When swift action needed, no explanation to passenger.
On the phone:
•Smaller field of vision, less focus and less scanning
•Takes more time to disconnect mentally
•You do not stop in mid-sentence
•You often add an “Excuse me I have…”
•Difference is half a second = double normal reaction time.
•At 70 km/hour (43,5 m) this is a difference of 10 meters (11 y) .
This is the difference between a close-call and an accident.

Multittaksing kids are worse
Multitasking children are not better
but worse at it than older people!
The more multitasking and taskhoping, the worse homework, worse grades,
worse concentration, worse thinking…
Better in fast information retrieval… which is exactly the next brainwork that
computers will take over very soon! It’s a low skill job.
To often they paste this information together, without much thinking, without
getting the quintessence.
Help them, guide them!
“It's not so much that the video game is going to rot your brain,
it's what you are not doing that's going to rot your life" Edward Hallowell

My Hypothesis: hyperconnectivity is only a problemfor older generations not for digital natives
What do you think?
Six discoveries in my review of the literature repudiate my idea
1. Hyperconnected youngsters are not ICT-savvy at all
2. hyper-connected youngsters are better at two skills, but these are low-level ICT
skills
3. young hypertaskers are just like adult hypertaskers: they are worse at multitasking,
not better
4. hyper-connected youngsters do significantly worse at school
5. hyperconnectivity has a negative impact on emotional and social development
6. hyperconnectivity of kids creates a new social divide
The sad overall conclusion: my original hypothesis is totally and utterly wrong.
Hyper-connected children perform worse intellectually, emotionally and socially and are
even worse at multitasking
The problem is not what kids do with ICT, but what they don’t do
A challenge for parents, teachers, managers and employers

Sleep duration disease
Slaapduur + gebrek
WHAT IS ENOUGH SLEEP-Healthy = 7-8 hours-For about 10% = <7 hours
Test If you really belong to the 10% or if you are deceiving yourself:
If you get through the day with less than 7 hours- Without stimulants: no caffeine, no coffee, no tea, no energy (LOL!) drinks.
- Without symptoms of sleep-debt such as:
difficult getting out of bed, feeling sleepy, feeling tired, nodding off, feeling drowsy while
driving!, needing a nap, craving for junk food or sugar after you had a normal meal,
sleeping extra hours in weekend
-Without brain symptoms such as:
Concentration↓ ↓ Memory ↓↓ Patience ↓↓Feeling for nuance ↓Insight ↓
Judgement ↓ Creativity ↓ Multitasking ↓ Decision capability ↓ Depression ↑ Moodiness ↑
Happiness ↓ Enthusiasm ↓ Sexual desire ↓↓↓… but do you remember how it used to be?
Then you are a real short-sleeper
Warning: first14 days without caffeine withdrawal symptoms M-54
