Gravitational waves have been instrumental in providing deep insights intothe nature of gravity. Next-generation detectors, such as the EinsteinTelescope, are predicted to have a higher detection rate given the increasedsensitivity and lower cut-off frequency. However, this increased sensitivityraises challenges concerning parameter estimation due to the foreseeableoverlap of signals from multiple sources. Overlapping signals (OSs), if notproperly identified, may introduce biases in estimating post-Newtonian (PN)coefficients in parameterized tests of general relativity (GR). We investigatehow OSs affect $-1$PN to 2PN terms in parameterized GR tests, examining theirpotential to falsely suggest GR deviations. We estimate the prevalence of suchmisleading signals in next-generation detectors, and their collective influenceon GR tests. We compare the effects of OSs on coefficients at different PNorders, concluding that overall the 1PN coefficient suffers the most. Ourfindings also reveal that while a non-negligible portion of OSs exhibit biasesin PN coefficients that might individually prefer to conclude deviations fromGR, collectively, the direction to deviate is random and a statisticalcombination will still be in favor of GR.
