If you were born in the 80s, 90s or before in India, this will sound familiar: a teacher’s danda across the palm, a parent’s chappal reaching for you mid-argument. It wasn’t cruelty, as most of us understood it growing up – it was just discipline. Normal. Expected, even.
I believed that too, for a long time. But the research on this – and there’s a lot of it – tells a very different story.
What the research actually says
The most comprehensive body of work on this question comes from Elizabeth Gershoff, a researcher at Columbia University. Her first major meta-analysis, published in 2002, reviewed 88 studies and found corporal punishment associated with ten negative outcomes in children – increased aggression, poorer mental health, weaker parent-child relationships, poorer moral internalization – against exactly one desirable outcome: increased immediate compliance (Gershoff, 2002).
In 2016, Gershoff and her colleague Andrew Grogan-Kaylor went further, analyzing 75 studies spanning 50 years, 13 countries, and 160,927 children. The finding held: spanking does not improve children’s behavior in the long term. It’s not linked to better moral internalization, not linked to reduced aggression. If anything, it’s linked to worse outcomes across the board (Gershoff & Grogan-Kaylor, 2016).
This is correlational research, not a randomized controlled trial – you can’t ethically randomize which children get hit for a study. But the consistency of the finding across five decades, a dozen-plus countries, and multiple independent research teams is about as strong as correlational evidence gets.
So if punishment doesn’t actually improve behavior – why does it cause harm? The answer lies in how a child’s brain responds to stress.
Not all stress is bad – but some of it is dangerous
I first came across this framework while studying at Harvard myself. Harvard’s Center on the Developing Child, led by Dr. Jack Shonkoff, has done foundational work on how children’s stress response systems develop. Their framework identifies three distinct types of stress, not a simple good/bad binary:
- Positive stress: brief, manageable challenges such as the first day at a new school, or an injection at the doctor’s office. With a supportive adult nearby, the child’s stress response activates briefly and returns to baseline. This is a normal, even necessary, part of healthy development.
- Tolerable stress: more serious difficulties such as the loss of a loved one, or a frightening injury. If it’s time-limited and buffered by a caring relationship, the child’s brain and body recover without lasting damage.
- Toxic stress: strong, frequent, or prolonged activation of the stress response – without a supportive relationship to buffer it. This is what causes lasting harm to developing brain architecture (Center on the Developing Child, Harvard University, 2020).
Punishment delivered in fear, especially repeated punishment without a secure, connected relationship to buffer it, risks pushing a child’s stress response toward the toxic end of that spectrum – the one Harvard’s own research identifies as damaging, not the manageable kind that’s a normal part of growing up.
Discipline through connection, not punishment
None of this means discipline itself is the problem. Children need boundaries – that part hasn’t changed. What the research actually challenges is the method: punishment versus connection.
Listening to a child. Understanding what they’re actually feeling. Relating to them instead of just correcting them. This is what the evidence points toward as the thing that actually works.
Here’s why the early years matter so much: India’s own National Education Policy 2020 states it plainly, in its opening section – “over 85% of a child’s cumulative brain development occurs prior to the age of 6, indicating the critical importance of appropriate care and stimulation of the brain in the early years” (Ministry of Human Resource Development, 2020, Section 1.1).
This is precisely why the policy places such heavy emphasis on Early Childhood Care and Education (ECCE) as a foundational pillar of India’s education system. Whatever the exact figure, the underlying point holds: the foundational years of a child’s life shape everything that follows. That’s precisely why how we respond to a child in those years – with punishment, or with connection — matters more than almost anything else we do as parents.
Two books worth reading
If you want to go deeper on this, two books are worth your time:
“The Whole-Brain Child” by Daniel J. Siegel and Tina Payne Bryson – a genuinely actionable guide to how a child’s brain develops and matures, with practical strategies grounded in neuroscience.
“The Danish Way of Parenting” by Jessica Joelle Alexander and Iben Dissing Sandahl – an exploration of why Denmark consistently ranks among the happiest countries in the world, and what its parenting culture (built around empathy and connection rather than punishment) might teach the rest of us.
