04 — Assumptions is the mother of all fuckups
§ 04
• why now?
The more automated the decision, the more dangerous invisible data becomes.
05 / 36
05 — Acknowledgement of imperfection
• Foundation
It is data we can rely on because we understand its source, transformation, and use.
06 — Russom, philip
06 / 36
Trusted data comes from selected sources, is transformed for intended use, and delivered appropriately.

• Where it hides
Invisible data lives in logs, dashboards, features, alerts, and “ground truth”.
08 / 36
08 — information decay
• Failure chain
The problem is rarely one bad number. It is accumulated uncertainty.
Invisible data problems are usually design problems wearing a statistical mask.
09 — Why should we care?

11 — Provenance
I
• playbook #1
Trust starts with provenance.
Source trust can come from rules, experience, or identity, but none of them remove the need for verification.
12 / 36
12 — data ≠ interpretation
II
• playbook #2
The same signal can lead to very different conclusions.

14 — data ≠ interpretation
15 / 36
15 — meaning changes
III
• playbook #3
Data changes meaning as it moves through systems.
16 / 36
III
• playbook #3
If the transformation history is invisible, trust decays even when the chart looks clean.
16 — meaning changes
If your training data is history, your model may automate history’s unfairness.
17 — bias much?
17 / 36
Ask where the asymmetry begins.
18 / 36
18 — Bias
• bias is often upstream
A red alert is still an interpretation, not reality. Developers know this from loose equality, noisy monitoring, and brittle thresholds.
19 / 36
19 — fake news
Some examples:

• Real world reminders
AI just multiplies the blast radius.

That makes governance a product design problem, not just a compliance task.
22 — fake confidence
• Why ai changes the stakes
22 / 36
Not as magical raw material, but as something constrained by reality, context, quality, and interpretation.
23 — constrainment
• key idea
23 / 36
Trustworthy systems are built by acknowledging boundaries, not hiding them.
24 — Acknowledgement
24 / 36
Use this as architecture, review, and ops language.
25 — Pillars
• five practical pillars
25 / 36
Validation should exist in code, pipelines, UX, and operations.
26 — trust, but verify
• Validation is a product feature
26 / 36
Make meaning machine-readable and human-visible.
27 — Failure is failure
• Semantics save systems
27 / 36
A number without semantics is a rumour with decimals.
28 — semantics
28 / 36
Keep it concrete.
29 — concrete
• Governance that engineers can love
29 / 36
Otherwise they become a rubber stamp.
30 — transparency
• HUMAN OVERSIGHT SHOULD BE DESIGNED, NOT ASSUMED.
30 / 36
31 — no faith
• Seven questions for every review
31 / 36
If you cannot answer them, trust is currently faith.
32 — Review
• Seven questions for every review
32 / 36
If you cannot answer them, trust is currently faith.
33 / 36
33 — earn it
• Maturity Model
Aim to move conversations left to right.
Trust is not a property of the data alone. It is a property of the whole socio-technical system around it.
Design systems that demand trust, not blind belief.
