Most poor decisions are not made by unintelligent people.
They are made by people who only looked at the problem from one angle.
PHISE gives you five angles, applied together, before you decide. It is not a checklist. It is a discipline.
THE FIVE LENSES
Each PHISE lens offers a different way of seeing a situation.
Together, they bring balance, structure and insight into your thinking.
P — Practical
Will this actually work?
The Practical lens tests feasibility. Before anything else, it asks whether a decision or solution can realistically be implemented given the resources, time, constraints and context available. Ideas that are brilliant in theory but impossible in practice are not solutions. The Practical lens keeps thinking grounded.
Ask:
- What is the realistic next step?
- What resources and capacity does this require?
- What breaks when this meets the real world?
- What is actually within our control?
Use this lens first to test whether any plan is actually actionable.
H — Horizon
What happens later?
The Horizon lens looks past the immediate outcome. It traces long-term consequences, second-order effects and the risks of decisions that seem right today but create problems tomorrow. Short-term thinking is the most common source of avoidable mistakes. The Horizon lens slows that impulse down.
Ask:
- What are the likely consequences in one, three, ten years?
- What does this decision make harder or impossible later?
- What feedback loops might this set in motion?
- What might we regret?
Use this lens to avoid decisions that solve today’s problem and create tomorrow’s.
I — Integrity
Can I stand behind this?
The Integrity lens tests fairness and ethical consistency. It asks not just whether a decision is legal or convenient, but whether it is right — and whether you would be comfortable if it were made fully visible.
Ask:
- Is this fair to everyone involved?
- Am I being consistent with what I say I value?
- Who bears the cost of this decision, and is that fair?
- Would I be comfortable defending this publicly?
Use this lens to test whether a decision is not just legal or convenient, but genuinely right.
S — Stakeholder
Who else is affected?
The Stakeholder lens maps the people behind every decision — those who will be affected, those whose interests conflict, and those who are missing from the conversation entirely. Decisions made without this lens tend to produce resistance, resentment or harm that could have been anticipated.
Ask:
- Who is directly affected by this?
- Whose voice is not in the room?
- Where do interests conflict, and how should that be resolved?
- What does each group actually care about?
Use this lens to ensure decisions account for everyone they touch — not just the people making them.
E — Evidence
What proof supports this?
The Evidence lens demands that decisions be grounded in what is actually known — not what is assumed, hoped or convenient. It tests the quality of data, the validity of sources and the robustness of the reasoning chain.
Ask:
- What do we know for certain, and how do we know it?
- What are we assuming — and have we tested those assumptions?
- What evidence contradicts our preferred view?
- What would change our mind?
Use this lens to ensure your reasoning is based on facts, not convenience.
How the Lenses Work Together
ReasonQ is not a checklist.
It is a way of slowing down your thinking so you can see the full picture.
The lenses are not applied in sequence. They are perspectives to move between freely, return to often and apply with honesty.
A decision that is Practical may strain Integrity. A Horizon perspective may conflict with what Stakeholders want today. That tension is not a problem — it is information. Good decisions acknowledge and address those tensions rather than pretending they do not exist.
