Increasing the alpha level increases the risk of a Type I error, which is rejecting the null hypothesis when it is actually true. This means that there is a higher probability of finding a significant effect when there is no true effect. However, increasing the alpha level does not affect the standard error, which is a measure of the variability of the sample means around the population mean.
