lol In reality, we know that they most certainly can and do. How about when that unshakable Fi conviction about a particular feeling/belief is rooted in untruth? And they take (excessive) action based on feelings (which aren't facts), the (limited) sensory data before them, strung together by a shaky hunch they're convinced is
the underlying truth (when their intuition is not a strength for them), and with little to no care about whether any conclusions based on the aforementioned make objective sense.
LIEs, along with most other intuitives, are prone to "scatter brained" fuck ups that may result in several missed phone calls, a misplaced or lost phone, a missed date/birthday/engagement, etc... with willful, intentional deception playing no active part and yet a ESI may be utterly convinced that LIE is cheating and doing a poor job of covering their tracks. lol As if LIEs are not excellent strategists capable of all sorts of capers and covert operations when and if we choose to be. But try to convince the ESI that you aren't lying. Even if they give in and say that they believe you, they really don't because whatever evidence they can literally see along with their experiences, matter the
most. They can most definitely fuck up a relationship all by themselves.
