  We evaluate the performance of the catalog-level blind analysis technique
(\textit{blinding}) presented in Brieden et al. (2020) in the context of a
power spectrum and bispectrum analysis. This blinding scheme, which is tailored
for galaxy redshift surveys similar to the Dark Energy Spectroscopic Instrument
(DESI), has two components: the so-called "AP blinding" (Alcock-Paczy\'nski,
concerning the dilation parameters $\alpha_\parallel,\alpha_\bot$) and "RSD
blinding" (redshift space distortions, affecting the growth rate parameter
$f$). Through extensive testing, including checks for the RSD part in cubic
boxes, the impact of AP blinding on mocks with realistic survey sky coverage,
and the implementation of a full AP+RSD blinding pipeline, our analysis
demonstrates the effectiveness of the technique in preserving the integrity of
cosmological parameter estimation when the analysis includes the bispectrum
statistic. We emphasize the critical role of sophisticated -- and difficult to
accidentally unblind -- blinding methods in precision cosmology.
