A new study has indicated that to err and learn from them is good for older brains.
The study suggested that finding things out the hard way - and taking steps not to make the same mistake again - is more effective than passive learning and specially benefits older brains.
This challenges evidence which maintains that making mistakes is bad for learning in older adults and passive "errorless" learning, where answers are given, is a better technique.
"The scientific literature has traditionally embraced errorless learning for older adults," the Daily Express quoted Dr Andre-Ann Cyr, of the University of Toronto, as saying.
"However, our study has shown that if older adults are learning very conceptual material, errors can actually be beneficial for the learning process," added Cyr.
The study has been published in the journal Psychology And Aging.
