11.2 Barriers to Communication and Cognitive Biases

Key Takeaways

  • Barriers to communication include organisational hierarchy, organisational culture, technology, amount of information, type of information, and attitudes and perceptions
  • Cognitive biases are filters people use when receiving communication
  • Confirmation bias is confirming one's own existing beliefs
  • Status quo bias is the preference for keeping things as they are
  • Availability bias focuses on more memorable or easily available information, and loss aversion means losses are felt more strongly than gains

Two distinct problems interfere with change communication: barriers that obstruct the message and biases that distort how it is interpreted.

Barriers to communication

CM3 names six:

BarrierHow it obstructs
Organisational hierarchyMessages passing through layers are filtered, softened or lost; upward messages especially so
Organisational cultureA culture where challenge is unwelcome suppresses the feedback the change team needs
TechnologySystems people cannot access, formats they cannot open, or channels not everyone uses
Amount of informationToo much and it is not read; too little and rumour fills the gap
Type of informationContent mismatched to the audience — technical detail to a general audience, or vague reassurance to specialists
Attitudes, perceptionsWhat the receiver already believes about the change, the sender and the organisation

Hierarchy and culture are the structural ones

Hierarchy degrades messages in both directions. Downward, each layer adds its own interpretation and omits what it considers unimportant, so the message reaching the front line can differ materially from the one sent. Upward, bad news attenuates at every level, which is why sponsors are often the last to learn a change is failing.

This is precisely the problem change agent networks solve. A network provides a route that bypasses the hierarchy in both directions — trusted, 'one of us' messages down, and unfiltered reality up.

Amount and type of information

These two are the barriers change teams create themselves. Amount is the more common failure: a change programme generating weekly bulletins, monthly newsletters, town halls and intranet updates produces a volume that guarantees none of it is absorbed. Fewer, better-targeted communications outperform more.

Type is a segmentation failure. A single message written to satisfy every audience satisfies none — it is too detailed for the general population and too vague for the people who need specifics.

Cognitive biases

Behavioural psychologists have identified many cognitive biases (Kahneman, 2012). These are the filters people use when receiving communication. CM3 examines four:

BiasDefinitionHow it shows up in change
Confirmation biasConfirming own beliefsSomeone who has decided the change will fail reads every setback as proof and discounts every success
Status quo biasKeeping things as they are"Why do we have to change everything? There are many systems that are still effective"
Availability biasFocus on more memorable or easily available informationOne vivid failure story from a colleague outweighs statistics from twenty successful sites
Loss aversionImpact of losses felt more strongly than gainsA change offering a clear net benefit is resisted because the specific losses are more salient than the diffuse gains

Distinguishing status quo bias from loss aversion

These two are easily confused because both produce resistance to change. The distinction:

  • Status quo bias is a preference for things staying as they are, expressed as a defence of the current state. "What we have works."
  • Loss aversion is about the asymmetric weighting of losses against gains. The person may accept the change is better overall but still resist, because what they lose feels bigger than what they gain.

A statement like "Why do we have to change everything? There are many systems that are still effective" is a defence of the current state — status quo bias.

Working with biases rather than against them

Biases cannot be argued away — attempting to correct someone's confirmation bias with more evidence typically strengthens it. What works is designing communication that accounts for them:

For loss aversion, name the losses explicitly and specifically before describing the gains. Unnamed losses loom larger than named ones, and acknowledging them removes the sense that the change team is hiding something. This is the same discipline as the dis-benefit conversation and the change-curve guidance not to minimise losses.

For status quo bias, do not attack the current state. Telling people that what they have built is deficient triggers defence. Appreciative Inquiry's approach — identifying what works well and building on it — is designed for exactly this, and it explains why AI increases motivation to change.

For availability bias, provide vivid, concrete, memorable positive examples rather than aggregate statistics. One credible story from a peer site who has already made the change beats a percentage.

For confirmation bias, the strongest counter is having the message carried by someone the receiver already trusts — a change agent from their own area — because the source is the thing their filter is applied to.

Barriers and biases together

A useful way to hold the two apart: barriers stop the message arriving; biases change what it means when it does. A message blocked by hierarchy never reaches the receiver. A message filtered by confirmation bias arrives fully and is interpreted as confirming what the receiver already thought.
