▶ Technical details

Research hypothesis

REPLICATION of exp-dilution-n7. Same parameters (N=7, 98 rounds, 14 rds/agent) with rotation=4 (original used rotation=0). Tests robustness of dilution finding across different speaking-order positions.

Pre-registered prediction: TR_range >= 0.45 (matching original's 0.522).

Experimental setup

Type: simple

Condition	Parameters
DILUTION_N7	persona: PERSONA, interaction: LIVE, n_agents: 7, n_rounds: 98, note: Replication 2. Rotation=4.

Factors: n_agents (7) × rounds_per_agent (14)

Parameters

n_agents: 7
n_rounds: 98
n_runs_per_condition: 1
model: gemini-2.5-flash-lite
temperature: 0.9
scheduler: round_robin

Trophic Ratios by Condition

Mean trophic ratio per agent across runs. Error bars = ±1 std dev. Higher TR = more upstream (exporter).
