Lensing Amplitude Bias (a_Lens=1.18)

The Cosmic Microwave Background measurements consistently show that the amplitude of gravitational lensing effects is larger than the Lambda-CDM model predicts, with the lensing amplitude parameter A_lens measured at approximately 1.18 when the standard model predicts a value of 1.0, representing a statistically significant excess lensing signal that persists across multiple independent CMB datasets and analysis methods. This excess indicates either that more matter exists between us and the CMB than the model accounts for, or that the matter is organized in ways that create stronger lensing per unit mass, or that some systematic effect in the observations or analysis is creating apparent excess lensing (Planck Collaboration 2018; Addison 2016). Lambda-CDM struggles with this bias because the model makes precise predictions about the amount and distribution of matter based on primordial density fluctuations and structure growth, and a consistent 18-percent excess in lensing amplitude either requires unaccounted-for matter (contradicting matter surveys), modifications to how matter clusters, or unknown systematic errors in multiple independent measurements that have all converged on the same biased value.
