Problem of basic trust

Trust is not tangible. It arises from expectations, repeated experiences, social cues and the interpretation of intentions. In low-contextual thinking, this process is often difficult, leaving basic trust fragile.
Difficulties in low-contextual thinking
- Difficulty sensing intentions behind behavior → interpretation happens mainly literally.
- Little tolerance for ambiguous or inconsistent signals → trust quickly collapses upon deviation.
- Limited change of perspective → difficult to think: "maybe he didn't mean it that way."
- Difficulty with pattern recognition over time → each event is more isolated.
- Expectations are not fulfilled by themselves → trust must be reaffirmed over and over again.
Examples
Case
A friend doesn't reply to a message once. The low-contextual person immediately concludes: "He is no longer interested." There is no room to consider context (busy, forgetting, other priority). Trust collapses immediately.
Case
A partner says "I trust you." The low-contextual person only experiences this at that moment. Because there is difficulty with timelines and linking behavior over the longer term, this trust must be explicitly confirmed again and again.
Trust over time
Essentially, trust builds through:
- pattern recognition in behavior over a longer period of time,
- integration of past, present and expectations for the future.
Because low-contextual people have difficulty with this type of integration, they experience trust as something that needs to be restored over and over again. Basic trust is therefore difficult to establish, and remains vulnerable in the event of minor disruptions.
What does the developmental perspective say?
The idea of basic trust is not new. Erik Erikson (1968) saw basic trust versus basic mistrust as the very first developmental task, in the first eighteen months of life. Attachment theory (Bowlby, Ainsworth, Main) developed this further into a large research field.
Izaki and colleagues (2024) discuss the neurobiological roots of the attachment system.1 Their overview is limited to specific brain regions and mechanisms; we strictly adhere here to what they actually discuss.
Trust and autism — what does the research say?
An old misconception is that autistic children cannot form attachments. That is incorrect. Teague and colleagues (2017) showed in a systematic review that autistic children do indeed form attachments — although the standard measurement method (the so-called Strange Situation, an observation procedure) is not without problems in this context.2
A recent meta-analysis by Trottier-Dumont and colleagues (2025) pooled 202 autistic children from six studies.3 Approximately 46% were securely attached, 19% avoidant, 9% resistant, and 27% disorganized (erratic, without a clear strategy).
An important nuance. The first three figures are close to the general population. Disorganized attachment is clearly elevated in some age groups. It is therefore not accurate to say that the picture is "fully comparable."
In adults, Sonfelianu and colleagues (2025) provided a systematic review of twelve studies.4 One caveat weighs heavily: almost 99% of the studied adults were women. The conclusions therefore cannot simply be extended to men. Taurino and colleagues (2025) mapped the broader research field.5
Epistemic trust: trust in the source
A related concept is epistemic trust: the ability to accept information from others as relevant and usable. Its restoration is seen as an active ingredient of psychotherapy (Campbell, Kumpasoğlu & Fonagy, 2024).6 Its loss is called epistemic petrification by Fonagy, Luyten and Allison (2015): an early relational rupture through which someone no longer uses communicated knowledge to update their worldview.7
A synthesis of our own, noted as such: context sensitivity is an ability that grows in safe relationships and can falter in unsafe relationships or with a neurobiological predisposition. Giving trust requires precisely the opposite of context blindness: being able to set context aside for a moment — "I trust you, even without proof right now."
Note: epistemic trust as a measurable variable is still young; its validity is still under development.
Overlap between autism, attachment disorders, CPTSD and EUPD
Similar complaints can belong to very different presentations: autism, attachment disorders, complex post-traumatic stress disorder (CPTSD) and emotionally unstable personality disorder (EUPD). Sarr and colleagues (2025) surveyed 106 international experts in a structured consensus study (a Delphi study) on how to distinguish these presentations.8
That produced 275 consensus statements about overlapping and distinguishing characteristics. Important: a Delphi study provides expert consensus, not empirical evidence. The final round moreover relied on 55 participants. Read the outcome therefore as a shared judgment of experts, not as hard evidence.
But note: the very attempt to neatly separate these presentations is itself a form of pigeonhole thinking. The fact that the complaints overlap so strongly is precisely the signal for us. From a contextual thinking perspective, the question is not "which box does this person belong to?", but "how does this brain process context — and where does it get stuck?" That question cuts across the labels. See also Context and DSM.
