The ignoring function is the foundation of your base, it's your strongest instinct and probably what you were born being good at. It has an effect on everything you do, and even if you tried to, you couldn't be totally unaware of information related to it.
For example, an SEI has

as their ignoring, so they are constantly picking up information about the sensory environment and filtering it to produce pleasant sensations (base

). They could not maintain their sensory homeostasis without maintaining an Se awareness at all times. It's the same for all types:
LSE -

ignoring - uses what they know of rules and procedures to guide their selection of the most effective techniques (

).
IEE -

ignoring - uses what they know about how processes change over time to select the best time to seize an option (

)
ESE-

ignoring - uses what they know about how people really feel to select the right words, facial expressions, etc. to create a shared mood (

)
The ignoring function is so (subconsciously) natural to you that you don't recognize its enormous impact on your life, and it tends to have a more obvious impact on others (again, subconsciously). It's constantly working to protect you from outside influences. When it doesn't work, the 8th function is recruited as a secondary aid. This all happens rapidly at an instinctive level, there is little to no conscious thought involved.
In a way, the ignoring sets limits on how one should live. But the standards apply to others more than to yourself. Thus, is it inherently hypocritical.

in SxI sets boundaries on physical force

in LxE sets boundaries on rules

in IxI sets boundaries on alternative possibilities

in ExI sets boundaries on emotional expressiveness

in SxE sets boundaries on personal comfort

in ExE sets boundaries on ethics
Under stress, when tired/drunk or otherwise less than fully lucid, the ignoring function is expressed strongly. It always tries to act in a way that least impacts the POLR, but under stress, possible impacts on the POLR can be completely ignored. It's as though the ignoring says to society "My way or the highway!" and
ignores convention. It fights to preserve the right to use that function however it wishes, and
denies the same right to others.
SLIs and SEIs become ruthless about appropriate use of force

ESEs and EIEs become ruthless about appropriate standards of ethics

IEEs and ILEs become ruthless about appropriate use of time

LSEs and LIEs become ruthless about appropriate adherence to procedure

ESIs and EIIs become ruthless about appropriate emotional expression

IEIs and ILIs become ruthless about appropriate use of alternatives

SEEs and SLEs become ruthless about appropriate use of sensual comforts

LSIs and LIIs become ruthless about appropriate use of resources
Thus the ignoring function has a dampening effect on others.
