 The nature of psychological studies / experiments doesn't include any sought of under average validity or reliability because it consists of behavioral changes and mind study. Its difficult to consider low reliabity while the reseacher is looking for specific outcome in consideration of the variables  affecting. Psychological findings are considered to be characterised by high reliability  and validity because the  experiment is known and the variable are also known.
