18  Research and Claim Ledger

This first edition contains a developed conceptual framework and a deliberately small evidence base. The ledger separates sourced claims from mechanisms and open propositions so later editions can become more empirical without retroactively pretending certainty.

18.1 Sourced claims

Table 18.1: Claims with an attached source in this edition.
Claim Status Source and use
Online-dating users report mixed motives; long-term partnership and casual dating are both common motives Sourced survey finding Vogels and McClain (2023). Prevents treating app presence as a character verdict.
U.S. respondents to the 2025 Stack Overflow Developer Survey reported high remote-work participation relative to several other top-reporting countries Sourced descriptive survey finding Stack Overflow (2025). Establishes remote work as relevant to the initial audience.

18.2 Evidence needed

The following claims are plausible and important but require stronger literature review before they should be presented as empirical conclusions:

  • repeated exposure and cross-context observation improve calibration of interpersonal trust;
  • social embeddedness predicts relationship stability after controlling for selection effects;
  • network redundancy reduces the probability of catastrophic reputation error;
  • remote work increases isolation specifically through loss of weak recurring contact;
  • high alternative salience reduces tolerance for ordinary relationship friction;
  • activity scaffolds with side-by-side time produce more durable ties than conversation-only mixers;
  • early institutional windows create path-dependent adult network advantages.

An “Evidence needed” marker does not mean a claim is false. It means the present edition has not earned the right to present the claim as established.

18.3 Mechanistic inferences

These propositions organize the book. They are reasoned interpretations rather than direct findings from a single study:

  1. Stateful channels reduce verification cost by carrying provenance and expectation of recurrence.
  2. Recurring institutions store coordination that individuals would otherwise recreate manually.
  3. Warm introductions change the experience of a match by adding borrowed context and reputational collateral.
  4. Cross-context relationships are more resilient because they have multiple routes to continue.
  5. Social redundancy reduces the load placed on any one friendship, partner, or group.
  6. Reputation changes how observers classify ambiguous events.
  7. Inherited policies can remain locally rational while becoming maladaptive in a new environment.

18.4 Hypotheses worth testing

Among adults with similar personality and baseline social skill, participation in a recurring activity with stable returners and side-by-side time will produce more retained relationships after six months than equal attendance at one-time social mixers.

The association between remote work and loneliness will be substantially moderated by membership in recurring offline institutions.

Dating-app use will predict lower relationship investment primarily among participants with continuous market exposure and high alternative sensitivity, not among all users.

People with direct ties across several network clusters will recover more accurately from a false reputational claim than people whose access to the graph depends on one gatekeeper.

18.5 Research practice for future editions

New claims should enter through this sequence:

  1. Write the claim narrowly enough to be falsifiable.
  2. Locate primary research or high-quality representative data.
  3. Record the population, method, effect size, limitations, and publication context.
  4. Distinguish association from causal evidence.
  5. Update the relevant chapter and this ledger together.
  6. Preserve unresolved disagreement rather than averaging it into false certainty.

18.6 Open questions

  • Which recurring activities produce the strongest bridge ties rather than only bonding ties?
  • How much recurrence is enough before familiarity stops producing new information?
  • When does social proof improve judgment, and when does it create prestige cascades?
  • Which maintenance rituals survive parenthood, relocation, and irregular work?
  • How do the framework’s mechanisms differ across gender, age, disability, culture, and sexual orientation?
  • Can deliberate adult rebuilding fully compensate for missing early compounding windows, and on what timescale?

The framework becomes more credible by showing its unfinished edges. A living book should update the confidence of a claim, not merely accumulate prose.
