Key takeaways
- Specify the future outcome and time horizon before calling a signal predictive.
- Separate event timing, detection timing and the client’s decision timing.
- A public announcement may arrive after counsel selection for one matter and before a different need.
- Evaluate false positives and missed needs, not only successful examples.
Hypothetical situation: a firm receives an acquisition announcement within minutes. The alert is fast, but transaction counsel may have been selected months earlier. A different integration issue may still be undecided. Leadership needs to know which opportunity the signal is supposed to predict before buying a claim of “earlier intelligence.”
Speed describes the delivery system. Predictive usefulness describes a relationship between evidence available at a particular time and a later outcome. Conflating them can direct investment toward faster distribution of information that does not improve a client decision.
Canonical definitions
Postilize uses these working definitions consistently across the Signals research collection.
- Predictive Signal
- A predictive signal is an observation used to form a testable expectation about a specified future client need or decision within a stated time horizon.
- Descriptive Signal
- A descriptive signal is an observation that reports an event or condition that has already occurred or currently exists, without itself establishing what happens next.
One observation, different claims
| Claim about an acquisition announcement | Classification | What remains to establish |
|---|---|---|
| An acquisition was announced | Descriptive | Source accuracy and event date |
| An unresolved integration issue may arise within a specified horizon | Predictive hypothesis | Whether the issue arises, when, and for whom |
| The announcing client will hire this firm | A stronger predictive hypothesis | Outside-counsel need, access, selection timing and firm choice |
| The alert arrived quickly | Delivery observation | Whether useful influence remained possible |
What makes a prediction testable?
State the target: a legal need emerging, a client considering outside counsel, an invitation to discuss an issue, or an engagement with this firm. These are different outcomes. Specify the observation date, relevant client population and time horizon. Do not change the target after seeing the result.
For the hypothetical acquisition, predict a particular unresolved integration need within a defined period, not “some legal work eventually.” Preserve the alternative explanation that the client’s internal team or existing advisers will handle it. A future legal need is not automatically future revenue for the observing firm.
What do practitioner observations tell us about timing?
The Conversion Window essay reports an anonymized practitioner describing developments before and after a formal proceeding, with the latter requiring a faster response. This illustrates why event stage matters. The account did not verify when clients selected counsel, so it cannot establish measured lead time.
The Conversion Window definition focuses on when a firm can still influence counsel selection. A descriptive signal can be actionable within that window. A plausible early prediction can be unusable if the firm lacks relevant capability or a credible route to the client.
How should firms evaluate a predictive claim?
Keep a dated record of all predictions, including those that do not lead to action. Define outcomes before evaluation and follow cases long enough to observe them. Compare with a simple baseline, such as the firm’s existing client-review process. Repeated reports of the same event should not inflate the sample.
Measure precision among flagged cases and examine missed needs among unflagged cases where outcomes can be observed. Separate earlier detection from earlier useful engagement. Do not treat “no matter for our firm” as proof that no legal need existed, or treat unavailable client outcomes as negatives.
Prevent hindsight from entering the record: information learned after a client decision cannot count as evidence available beforehand. Report selection bias when only pursued cases have known outcomes. Without that discipline, successful anecdotes can make a descriptive process look predictive.
What investment decision follows?
Ask a supplier or internal team to demonstrate the chain from observation to specified outcome and to useful client action. If the problem is detection after selection, faster routing alone will not resolve it. If detection is timely but action stalls, more prediction may not address the binding constraint.
In the acquisition example, stop treating the transaction announcement as proof of an open transaction mandate. Qualify the separate integration hypothesis with the relationship team. The decision can be to monitor rather than pursue; that is an appropriate result when uncertainty remains high.
Evidence and limitations
These are working analytical definitions. This page presents no validated predictive model, benchmark or measured advantage over descriptive monitoring. The evaluation design is proposed future work. Predictions about client behavior remain uncertain, and the published exploratory timing account cannot establish causality or generalize across practices.
