<｜begin▁of▁sentence｜>### Instruction:
As an intrepid foreign correspondent, you've been tasked with analyzing the intricate power dynamics within a certain political landscape. The relationships among key players have been mapped out in a political network resembling a graph with connections—let's call them 'political edges'—that include alliances and influences amongst individuals numbered 1, 2, 3, and 4. Notably, individual 4 has been observed to engage in self-referential actions, akin to a self-loop in this network diagram.

The political edges are specifically laid out as follows: (1, 2), (1, 3), (2, 4), (3, 4), and a notable circular dynamic where (4, 1) completes the loop back to the start. Intriguingly, this also includes individual 4's self-loop, which is a rare occurrence, denoting an introspective or perhaps self-sustaining tactic.

Your mission, should you elect to accept it, involves deploying a metric termed the 'trophic incoherence parameter,' a concept borrowed from the depths of network science, to quantify the extent of disorder in the hierarchical structure of these political relationships using the 'networkx' library. Could you shed light on how you could employ this intriguing function, given the data at hand, to interpret the level of systemic incoherence what with the self-loop of individual 4 factored into the calculation? This dimension of your report could offer profound insights into the stability—or potential volatility—of the underlying political structure.
### Response:
import networkx as nx
from networkx.algorithms.dag import trophic_incoherence_parameter

G = nx.DiGraph()
G.add_edges_from([(1, 2), (1, 3), (2, 4), (3, 4), (4, 1)])
q = trophic_incoherence_parameter(G, cannibalism=True)
print('Trophic incoherence parameter:', q)
